That's the best quote...My second fav is probably:
Captain Mandrake: Colonel, Colonel, I must know what you think has been going on here.
Col. Guano: You wanna know what I think?
Captain Mandrake: Yes.
Col. Guano: I think you're some kind of deviated pervert. I think General Ripper found out about your pervertion, and you were organizing some kind of mutiny of perverts.
(bah, typos in the quote I had saved)
