Animal House1978

Otter:
We need to do something.

Boon:
We do.

Otter:
You know what we need to do?

Otter and Boon:
Toga party.

Hoover:
We're on "double-secret probation," whatever the hell that is. We can't afford to have a toga party.

Otter:
You guys up for a toga party?

Bluto:
TOGA! TOGA!

Otter:
Ah, I think they like the idea, Hoov.

Hoover:
Otter, please don't do this.

Otter:
I've got news for you, pal. They're gonna nail us no matter what we do, so we might as well have a good time.

[Otter and Bluto lead the Deltas in a growing chant of "Toga! Toga! Toga!"]
