Leela: Look, I'm going down to Vergon 6 to save those animals whether you like it or not.
Zapp Brannigan: Go ahead. I won't stop you.
Leela: Threaten all you-- Wait. What?

Well if the oxygen holds out we might live long enough to starve to death.

Farnsworth: I need it shipped to my office at Mars University. It's a little experiment that may well win me the Nobel Prize.

Fry: The Moon? The Moon, Moon? Wow! I'm gonna be a famous hero just like Neil Armstrong and those other brave guys no one ever heard of!

Telephone voice: Collect call from-
Bender: I'm not giving my name to a machine!
Leela: I'll accept.

Leela: You're Fry's relative. Do you have any idea how he got so crazy?
