Amy: Bender, you can't be an Ultimate Robot Fighter. It's the most brutal form of competition in the galaxy!
Bender: It is?
Farnsworth: There are no rules. Two robots enter, one robot leaves. Then later the other robot leaves after being declared the winner.
Bender: Well, that doesn't sound so bad.
Farnsworth: Oh, did I mention the crippling, agonising pain? I'm pretty sure I did. Oh, yes, definitely.
