Bart: Actually, we were just planning the father-son river rafting trip
Homer: (chuckles) You don't have a son.

(Krusty Burger in the middle of the sea)
Guy: We tried to tell you these are unmanned oil rigs.
Krusty: Ah, close the damn thing down, no one's ever going to come.

Homer: Explain how!
Homer's Brain: Money can be exchanged for goods and services.

Bart: Aw, I'm out of money.

Security Man: Caucasian males out of money in sector four. Go to code red.

Bart: Oh, man, how are we supposed to kill the rest of the afternoon?
