moon rising tonight's "jimmy kimmel live" is brought to you by these tourists. lying down on hollywood boulevard. that's fun and gross. >> dicky: from hollywood, it's "jimmy kimmel live"! tonight, liam neeson "science bob" pflugfelder and music from old dominion. and now, here we go again, here's jimmy kimmel! [ cheers and applause ] ♪ >> jimmy: i'm jimmy, i'm the host. thank you for watching. thank you for coming. we've got a big fat show for you tonight and we will start tonight as usual with our president who say what you want about him, he makes every day interesting, he really does.

president trump tweeted this morning as part of one of his paranoid anti-media rants the people were pro-trump, virtually no president has accomplished what we have accomplished in the first nine months, an economy roaring. he's right, no president has ever accomplished what he's accomplished. after nine short months we have more nuclear weapons pointed at us than ever before in the history of the united states. the president is overcompensating a bit because he had a rough day yesterday. a candidate he worked very hard to endorse in alabama lost his election. senator luther strange lost his republican primary runoff to ray moore by 10 points which was very disappointing for the president. usually when trump goes all-in on a loser it's a casino with his name on it, at least he makes some money. [ cheers and applause ] it was an embarrassing blow to his ego. he even went so far as to do something he never does, he deleted three tweets today, tweets in which he bragged about how well luther strange was

doing as a result of his endorsement. the guy who won, roy moore, got his big endorsement from phil robertson of "duck dynasty," in case you worried america wasn't officially a reality show yet. roy moore is a terrible person. he called the 9/11 attacks divine intervention and hates homosexuals, he hates gay people so much there is literally no way he isn't one of them, i mean, he has to be. [ laughter ] roy moore actually called for outlawing homosexuality. not gay marriage. gay. okay? and pulled a handgun on stage at a campaign rally. so of course donald trump today tweeted, he sounds like a really great guy who ran a fantastic race. so who says he isn't across the aisle. in between failing with luther strange, who is by the way back to work trying to kill superman, and the failed graham-cassidy health care bill, it has been a bad week for donald trump. but he's not one to admit defeat. he was full of both "b" and "s"

today at the white house. he tried to claim they have the votes to beat obamacare. >> i just wanted to say on health care, we have the votes for health care. >> jimmy: no, you don't, but go on. [ laughter ] >> we have one senator that's in the hospital. he can't vote because he's in the hospital. i'm almost certain we have the votes. but with one man in the hospital, we cannot just claim that we have them. we have the votes. we can't do it now because we have somebody in the hospital -- >> sir, who's in the hospital, which senator are you referring to? >> he can't come here himself. in other words, he can't come here and vote because he's in the hospital. >> who is in the hospital? >> jimmy: he doesn't know who's in the hospital! [ laughter ] [ applause ] somebody's in the hospital, okay? why do you keep asking him who's in the hospital? the senator whose name he couldn't come up with is thad cochran of mississippi. who moments after that comment tweeted, thanks for the well wishes, i'm not hospitalized. [ laughter ] i'm recuperating at home in mississippi and look forward to returning to work soon. there was no senator in the

hospital. even if he was there was still at least three other republicans against the bill which means graham-cassidy wouldn't have passed whether he was in the hospital or not. to recap, mr. president, there was no senator in the hospital, you didn't have the votes, the bill didn't pass and you're bad at math, okay? [ cheers and applause ] this is funny. jared kushner, who of course is trump's adviser/son-in-law, someone looked into this, noticed jared is registered to vote in the state of new york. and you see as gender female, as a woman. this is his official voter registration card. gender, female. party affiliation is none declared. that's right. he's not a republican or democrat. he's just an independent woman. [ laughter ] [ applause ] he's registered as a woman in new york and in new jersey he's registered also, as "gender unknown." which according to his father-in-law means he can't serve in the military.

[ laughter ] but how good is that? jared kushner registered to vote as a woman? and he used the private e-mail server for white house business. i say lock her up! lock her up! [ laughter ] [ cheers and applause ] lock her up! so the president, he traveled to indianapolis today to give a sneak preview of his new tax plan. but i'm sorry, you shouldn't be allowed to release a tax plan until you've released a tax return. but he did anyway. he had a lot to say about this tax plan. he made a lot of claims, he threw out numbers, he talked about how much it costs to build the white house fence. olowissle to digest. edition of "drunk donald trump." [ tape playing slowly ] >> so i said, how much is the fence you're talking around the white house? sir! the fence will cost approximately $50 million.

i said, what? i kid you not. [ cheers and applause ] >> jimmy: why would he kid? the president is also doubling down on his war against the nfl. i should probably note trump has been ranting and raving at football players who chose to kneel during the national anthem to protest racial injustice. he's very opposed to men getting down on a knee, for good reason, every time he does it he winds up married to a woman who hates his guts. [ laughter ] the president called for boycott of teams that allowed these peaceful demonstrations, telling people to turn off the tv. how hilarious that trump supporters now have to stop watching football, bet you didn't see that coming. [ laughter ] if trump can't convince you to join his crusade, maybe you'll be swayed by the powerful story of discrimination shared by former notre dame football coach lou holtz. >> how do you think the coaches and the owners are handling this controversy this week? >> well, i think it's a real

problem. and the reason is this. that it's a workplace environment. it's just like working with walmart. you're in a workplace, you have certain obligations in trying to please the customers as best you can. i think that there's an awful lot of things that happen in this country, but i want you to know, i've been unfairly ticketed. i was given a ticket when i didn't exceed the speed limit because i was coaching at one school and the patrol officer graduated from the other and he let me know he was bitter. that happens in life. >> jimmy: you see, lou has been the victim of discrimination too. [ light laughter and applause ] >> jimmy: not only did the cop give him a ticket, he confiscated his teeth! [ laughter ] [ applause ] and you don't see him protesting! you know who else weighed in? on the nfl? all the way from russia, where he is now inexplicably a citizen, none other than steven seagal. >> i think it's outrageous. i think it's a joke. it's disgusting. and, you know, i respect the american flag. and i myself, you know, have

risked my life countless times for the american flag. >> jimmy: right, he risked his life twice, actually. once in "under siege," another time in "under siege 2." how dare these athletes disrespect his sacrifice? [ applause ] steven seagal also defended russia's interference in the u.s. election using the old "everything's doing it" defense. >> every country is involved in espionage. every single country. the americans spy, the british spy, the russians spy, we all spy on each other, let be honest. however, for anyone to think that vladimir putin had anything to do with fixing the elections or even that the russians have that kind of technology is -- is stupid. >> jimmy: hold on, i need to hear him say vladimir putin again. >> vladimir putin. [ laughter ] [ applause ] >> jimmy: dubbed in someone

else's voice, that is the best, i love that. he looks great too, doesn't he? [ laughter ] why does he look like -- he doesn't look like steven seagal. looks like somebody who went to cvs and bought a steven seagal costume on the way to a party. all right. it's time to get serious. last night on the show i spoke up about an issue i feel very strongly about, an issue that could affect our lives for many generations to come. i urged you to call your congresspeople to tell them to put a stop to this. pumpkin spice pizza. this is a real thing from a restaurant chain called villa italian kitchen. it is the latest atrocity in what i call the pumpkin spicing of america. we have pumpkin spice in everything now. pumpkin spice almonds, waffles, m&ms, ice cream, cream cheese, oatmeal, toaster strudel, there are pumpkin spice marshmallows, english muffins, oreos. we even have a pumpkin spice president for god's sake. [ laughter ] [ cheers and applause ]

it's too much. it is too much. and i was going to leave that alone, but now that we have pumpkin spice pizza, something has to be done about this, somebody has to stand up -- >> hey! i'm never going to stop, jimmy kimmel! pumpkin spice is going to take over the world! >> jimmy: who are you? >> pumpkin spice. i'm pumpkin spice, bitch. you know you're going to bow down because this is my time. >> jimmy: no, no, i'm not. listen, mr. pumpkin spice -- >> call me pump daddy. >> jimmy: listen, pump daddy, you're totally out of your lane here. you can have coffee, you can be in muffins, i'm okay with pumpkin spice oreos. please, i'm begging you, stay off pizza. >> stay off pizza! oh, pizza's just the beginning, sucker. i'm working on pumpkin spice french fries. pumpkin spice bacon. pumpkin spice pickles. pumpkin spice hot pockets.

>> jimmy: pumpkin spice hot pockets? >> pumpkin spice underpants, pumpkin spice lego batman, pumpkin spice q tips. pumpkin spice prilosec, pumpkin spice security guards. >> jimmy: what is a pumpkin spice security guard? >> see for yourself, over there, look. [ applause ] >> jimmy: oh, no. no, no, no, no, no. what the hell have you done to my guillermo? >> he's my ga-lair-mo now. >> jimmy: guillermo. >> i just spice them up a notch. >> jimmy: i don't like that at all. >> hey, my girl wants to be on tv. nutmeg, get in here! >> hey! >> jimmy: hi, how are you doing? >> isn't she fine? >> jimmy: she's great. >> honey, tonight you're getting a trick and a treat. now carry me the [ bleep ] out of here. >> jimmy: oh, come on now. well, i'm happy they found each other. all right. we are going to -- [ applause ] are we going to go with that for the whole rest of the show or what? >> guillermo: no way.

we're number one. [ cheers and applause ] serious thing, they say a number of factors are fueling this new epidemic. but mostly it comes down to tinder and "bachelor in paradise." [ laughter ] did you ever carry a condom in your wallet? guillermo, do you carry a condom in wallet? >> guillermo: never did. >> jimmy: i never did either, i was always a realist, you know? [ laughter ] today i was wondering if people still do it. i thought it would be a good question to ask folks on the streets. this afternoon we went outside, asked people, are you carrying a condom on you? this is a game. the way it works is, we will see an individual, say hello, and then based solely on that introduction, we will guess, together, whether that person is holding a condom. okay? got it? let's begin. >> hi, what's your name, where are you from? >> larry thomas from los angeles, california. >> are you carrying a condom on you? >> jimmy: is larry from l.a. -- seemed like he was holding a blunt in his hand or is that my imagination? is he carrying a condom? everyone says yes, let's find

out. >> yes -- no, sir. >> jimmy: he had to think about it for a second. next up. >> what's your name, where are you from? >> evan hand from chicago, illinois. >> are you carrying a condom on you? >> jimmy: is evan from chicago carrying a condom? everybody says no. let's find out. >> i'm not. >> why not? >> i'm here for abstinence and purity, sunshine.

inside the root, lasers gently clean out the canal with pulses of light. >> whoo-hoo! >> you said it, han. thanks to pips, root canal treatments are easier and more efficient than ever before. [ "star wars" theme music playing ] there's no more need to fear root canal treatment. laser dentistry is faster, less invasive, and much more comfortable than with traditional drills. look at how well it fixed this insurmountable problem from the dark side. you all may have the force, but i have pips. >> jimmy: wow.

that? >> you'll see why. because i've poked a tiny little hole inside of one side, the yellow side, another one inside the black one. >> jimmy: okay. >> what we want to do is fill it up with liquid nitrogen as much as we can. and then when it expands, jets of nitrogen gas will come out of here, that should cause it to spin around. >> jimmy: awesome. >> grab a little clamp here. >> jimmy: okay. >> we're going to -- pick up one of those. >> jimmy: all right. >> it's a yellow and black, kind of helps us know whether or not it's spinning. >> i see, very good. >> go ahead and dip that so it's wholly submerged. >> jimmy: okay. >> submerge that in, i'll get one too, another one. now because the air in there is compressing, it's drawing in the liquid nitrogen. >> jimmy: yeah, i know. [ laughter ] >> get a little bit in there. all right. and that should be good enough. go ahead and pop that into that tray there. >> jimmy: okay. what if we put one in the frying pan? would anything crazy happen? oh, look at that. >> isn't that great? >> jimmy: that is good.

[ applause ] >> you can see that spinning effect. >> jimmy: yeah. all right. >> there we go. >> jimmy: and now we have? >> i'll show you a different version of it. >> jimmy: okay, good, all right. >> this is a larger version of a hiro's engine. normally they'd put a little water in here. they'd put steam. then we have opposing jets here that would then spin it around. but we don't really have time for the whole heat thing. >> jimmy: okay. >> so we are going to use our liquid nitrogen. >> jimmy: thank you. >> all right. >> jimmy: you know it gets serious when the masks come out. >> oh, yeah. now here's the thing. you enjoy chocolate milk? >> jimmy: what? >> chocolate milk. >> jimmy: can't hear you. >> chocolate -- let's say you go to make a little bit of chocolate milk, right? >> jimmy: this is not how i do it. >> this is not? >> jimmy: no, we use a spoon. >> oh, well see, that's the thing. what if you don't have a spoon? here, take that. >> jimmy: all right. >> so pour in chocolate milk -- i don't know how much chocolate you like in there. >> jimmy: a lot is the answer. all right. >> that's good. >> jimmy: okay. >> all right. so what if you want chocolate milk and you don't have a spoon? you don't have a spoon, but you do have a 12-inch stainless steel sphere and liquid nitrogen. this is the way to go. >> jimmy: okay. >> would you measure, fill that

cup with liquid nitrogen. >> jimmy: where will we get liquid nitrogen? right here. >> go to your pantry. now we're going to pour that into our hiro's engine. >> jimmy: okay. >> there we go. oh, yeah, it's going in -- >> jimmy: is that enough? >> yeah. >> jimmy: let's do all of it. >> oh, man. >> jimmy: yeah. let's really blow the lid off this thing. okay, all right. >> which we actually might do. >> jimmy: okay. >> all right, there we go. >> jimmy: again, we're making chocolate milk. [ laughter ] at the end of this demonstration, there will be a glass of chocolate milk. >> let's see if we have any better luck. give it a head start. oh, i think -- i think it's -- oh, i can feel it now. >> jimmy: yeah. oh, yeah. oh, yeah. we're going, jimmy. >> jimmy: it's going. >> look at it! >> jimmy: here we go. [ cheers and applause ] >> wow! >> jimmy: oh my god, it's going

to blow! >> i think it's working! oh my goodness! i think it's working. wait! maybe we put too much in. >> jimmy: hold on, i'll get the tongs! >> i'm going in, i'm going in. hold on. aah! [ cheers and applause ] >> jimmy: it's incredible! >> yes! [ cheers and applause ] >> jimmy: when we come back, we're going to have fire when we come back? >> there will be fire. >> jimmy: we're going to have fire when we come back, we'll be right back.
