Marvin: Look, look, no, just think. They left me - an ordinary, menial robot - to stop you - a gigantic, heavy-duty battle machine - whilst they ran off to save themselves... What do you think they would leave me with? Frogstar Robot: Well, er, something pretty damn devastating I would expect. Marvin: Expect? Oh yes, expect. I'll tell you what they gave me to protect myself with, shall I? Frogstar Robot: Yes all right. Marvin: Nothing. Frogstar Robot: What? Marvin: Nothing at all. Not an electronic sausage. Frogstar Robot: Well, doesn't that just take the biscuit!
