I uh like forget which epichoad this is from but the best line was when B&B were on that like uh start-track enterprice:
Butt-Head:(to that one chick) "I order you to take off your dress and show me your thingies."
Beavis: "But captain that would violate inter-gal-actic law or something."
Butt-Head: (pointing) "Number one, I order you to go take a number two."
They actually showed this scene on David Letterman.
