"nightline" is next. good night.

tonight on "nightline." parental supervision required. there is some juvenile partying going on at chuck e cheese, and it is not the kids. why are the grown-ups behaving so badly? is the combination of parents, and booze causing problems? >> mclemorris not your usual sensation, he is telling us about his road to fame and why he is glad he broke all the rules. and sex in high school. this teen cheerleader faces jail time if convicted for having sex with a younger teammate. thousands petitioning on her behalf. and prosecutors seem to be

listening. are the laws too severe? keep it right here, america. "nightline" is back in just 60 seco

cou . from new york city, this is dan abrams. good evening, when you think of the chuck e cheese, you think of games and maybe the mascot. it is directed at kids, but then there is alcohol, and adults playing dirty. there are brawls from wisconsin to pennsylvania. why? nbc's nick watts looks at the restaurant. >> reporter: all his family and friends gathered around. then bang, it all kicks off.

can you hear happy birthday in the background? this happens, and not in frequently, bare-fisted fights. late last month, a mass brawl at a chuck e cheese during a kid's party. and it is the adults fighting. one woman holding a baby in one arm, swinging with the other. and there, that is the little girl trying to stop the grown-ups from fighting. >> a lot of parents can be very stupid and ridiculous. >> it is a disgrace. should not happen. >> reporter: but it does, a lot. type chuck e cheese into youtube, and you can watch wide-eyed as cell phone video catches the parties going very

sour. i'm in chuck e cheese right now. i'm enjoying myself, a pretty nice environment. so there is nothing wrong with chuck e cheese itself, so what is making these people go nuts? she was attacked at a chuck e cheese during her daughter's birthday party. >> and all i remember is actually hitting the floor and my hair being just ripped, ripped, ripped and being kicked in the head. the lady was angry about my children being on the picture machine so long. >> reporter: in pennsylvania, the cops were all too frequent visitors to chuck e cheese. >> we had about an 18-month period where we were there 17 times. >> reporter: at this chuck e cheese in wisconsin, two women were arrested following a mass brawl involving 20 people, sparked, according to the police report by one child taking too long to choose a toy. just a week later, at the same

restaurant, a father and daughter were arrested after a fight at a family birthday party. witnesses told police the man hit his 20-year-old daughter on the side of the face three times. chuck e cheese would not give us an interview. but they sent us a statement. while even one incident is too many, over 99.99% of the approximately 65 million annual guest visits at chuck e cheeses go without incident. and regarding those recent fights at komack and brookfield, they told us they have reduced showroom seating and party perimeters in response to recent incidents. >> you can prepare staff to see these tensions before they arise between children and step in. >> reporter: we asked two psychologists to watch some of these fights on youtube. do you find this behavior surprising? >> not really. birthday parties are really emotional situations.

>> reporter: heightened emotions, happy or sad, quickly bring emotions. and add to that, you spent all you had to make your kid's day special. >> if you have very limited resources and this is your one opportunity to state or show how good a parent you are, then it is very stressful. >> reporter: and that stress, says steven, quickly can turn violent. >> the fact that your family is judging you on how well you do this, the fact the children are looking at you for a good time, the fact they have been talking about it. >> reporter: into this noisy, crowded area, throw in alcohol and loosened tempers and you're asking for trouble. try wedding and fight in youtube, a reminder that families don't always get along. >> when you have family members coming for a birthday party and perhaps it was a divorce situation or a separation where

there was already uneasy feelings between family members, which are longstanding and for some people, still ongoing. you really sometimes have a -- a powder keg. >> reporter: chuck e cheese management realizes this is a problem. they told us they spent $15 million to date on efforts to stop situations like these. we are implementing the guest code of conduct as well as a rigorous test for security measures. but they could stop selling alcohol at kids' parties. here is another posting, they claim one of the fighters was actually pregnant. >> the more people you have in a room, that means more people using the games and activities, you can have conflicts about access to play. >> reporter: remember the movie mad max? they fought over limited oil.

in "water world," they fought over scarce, dry land. in a noisy, crowded chuck e cheese, they often fight over limited access to the games. >> we are that close to a breakdown in society that a situation at chuck e cheese can tip us over the edge. >> reporter: hockey games, soccer, political events, even black friday sales. >> there is an infusion of irresponsibility. >> reporter: in london, the situation ended in city-wide mayhem that lasted days. the rules humans live by every day were forgotten in an instant. and the way us humans were wired, you know what? this environment at a kid's birthday party, the noise, crowd, stress, chuck e cheese has all the makings for a powder keg. and all it takes is one spark to let it explode. i'm nick watts for nearly, in

we had no money at all. we were both living at home. >> for ben, life is completely changed. he is a mega celebrity now. >> reporter: the man with the pipes behind it. >> i'm going to pop some tag. only got 20 dollars in my pocket. >> reporter: is an endlessly friendly 51-year-old who dreamed about giving up hope of a music career years ago, and gone to work for microsoft. then, mclemore called. >> for me, this is rarified air, this is dream come true stuff. i am living a dream that i have had literally since 1968. >> i'll wear your grand dad's clothes ♪ i'm look incredible. >> this is not an often song that anybody would do really, really well. i was surprised. everybody here was surprised. the song about second hand shopping. >> reporter: it is a recipe they were told would never work. including their subject matter.

>> i might not be the same, but that is not important. no freedom until we're equal. >> reporter: that song is an anthem to same-sex marriage. and other personal struggles with addiction. and a number of songs about just being yourself. so singing about same-sex marriage, trying really hard, never giving up. being frugal. i mean, you know, that is not exactly the recipe to rap stardom. >> no, but it is my recipe, and i think that it is my recipe, why people identify with it. it takes soul-searching and using the paper and pen and turning it into a form of therapy. >> reporter: mclemore has done nothing by the book. >> this is the moment ♪ >> reporter: the band's second chart-topping single "can't hold us," features a 20-something-year-old singer who wouldn't join unless his grandmother approved.

a plea offer for a young woman accused of sex with a classmate, and a paparazzi member gets a stunning scoop. it is tonight's "feed frenzy." >> out in the open, when it comes to coming out, there is no time like the present. it seems that is how wwe superstar darren young felt. at the airport yesterday, a tnt

of prison time. her family says it was at that time when they were both women. >> they happened to be of the same sex involved in a relationship. if this case were a boy and girl, we don't believe it would have gotten that attention. >> maybe so on the media attention, but what about the authorities? would they have charged them if she was a he? >> if this was a boy and girl, they would have been prosecuted the same way. >> now they're urging katelin to accept a deal that would put her on probation for a year, and she would have to agree to avoid contact with her friend. that is far more lenient than the one she would have rejected in may, and she would have remained under house arrest. if hunt goes to trial, she faces up to 15 years in prison if convicted. the statutory rape laws are

confusing and often conflicting on the age requirements. 12 states have a single age of consent. meaning if you're below that age you can't consent to sex under any circumstances. in massachusetts, that is 16. but in new jersey, while the age is 16, as well, kids who are at least 13 can legally have sex if the other person is fewer than four years older. in nevada, the age of consent is 16, too, but sex with somebody under 16 is only criminal if the other person is at least 18. boy, but in almost every state, there is a scenario whereby two high school students could have sex and one ends up prosecuted and then potentially on a sex offender registry for a long time, much of the time turned in by the parents of the younger person. what do you think? should an 18-year-old be prosecuted for having sex with a 14-year-old or
