Squidward: Sponge, we've got to eat something.
SpongeBob: I've heard in times of hardship, the pioneers would eat coral.
(Squidward chomps on a reef)
SpongeBob: No, maybe it wasn't coral...
(Squidward barfs the coral)
SpongeBob: Maybe it was sand, no, mud.
Squidward: Gimme that pizza!
SpongeBob: Wait, I remember now, it was coral!
