"Dude, Cartman, look! Your mom is on the cover of Crack Whore magazine!" - Kyle Broflovski.
Kyle: Dude. You have sex with children.
NAMBLA Leader: We are human. Most of us didn't even choose to be attracted to young boys. We were born that way. We can't help the way we are, and if you all can't understand that, well, then, I guess you'll just have to put us away.

Kyle: [slowly, for emphasis] Dude. You have sex with children.
Stan: Yeah. You know, we believe in equality for everybody, and tolerance, and all that gay stuff, but dude, f*** you.
Kyle: Seriously.
