Doofy: Mom said that when I wear this badge you're supposed to treat me like a man of the law.
Buffy: Well, mom also said for you to stop sticking your dick in the vacuum cleaner.
Cindy: You've seen too many TV shows!
Ray: No! Watching TV shows doesn't create psycho killers! Cancelling TV shows does! [Ray starts stabbing Bobby]. Waynes Brothers was a good show! It was a damn good show! And, we didn't even get a final episode!
Shorty: I'm on TV! Oh shit! First Cops, now this! I'm gonna be a star, son!
Ms. Man: Come in, dear. Have a seat. Take off your bra if you like.
Buffy: I'm more of a people person. I'd rather help my fellow man than some animal.
Homeless Man: Spare a dollar?
Buffy: Ew! Get away from me you bum!
Cindy: Buffy!? Can't you see that he's just hungry? Here you go, sir. A nice sandwich.
Homeless Man: I said a dollar, bitch!
