onto the website, you can call the department of health, you can call the fire department, call lenox hill hospital, i'd be more than happy to give you the number. >> please do. >> because this is getting to the point, now, where you're harassing us. >> oh, i don't think that's the case, not if you're polluting my neighborhood, sir. >> well, you know what, we're supposed to be in your neighborhood according to the fire department regulations, in a 3-block area. there's an ambulance on 79th street, there's an ambulance on 59th street, and if somebody drops dead on that corner and goes into cardiac arrest-- >> then i'm glad we're having this conversation. >> so am i. >> [speaking english] >> because i'm really getting tired of it. >> well, you know, i'm tired of the air pollution in new york city, and that's why i'm doing what i'm doing. >> all the cars, and the trucks, and the 18-wheelers going by, they don't pollute the air? >> unfortunately, people can't idle for more than 3 minutes in the city of new york without violating the law. >> that is the law.
