Darcy: You look kind of young.
Bart: Uh, yeah, I have that disease that makes you look like an old man, but they gave me medicine for it and I took too much.

Bart: (Crashes through window) Party's over, Serpent.
Wiggum: No kidding, you're standing in the dip.

Lisa: Uck! This is the most disgusting place we've ever gone!
Bart: What about Brazil?
Lisa: After Brazil.
