Movie Quote from Galaxy Quest

Gwen: [Gwen and Jason encounter the chompers] What is this thing? I mean, it serves no useful purpose for there to be a bunch of chompy, crushy things in the middle of a hallway. No, I mean we shouldn't have to do this, it makes no logical sense, why is it here?
Jason: 'Cause it's on the television show.
Gwen: Well forget it! I'm not doing it! This episode was badly written!
