Goof: When Prince John's bath duck goes down the drain, you can see the duck is attached to a metal pole.
Renaldo: (he and Robin are facing a firing squad of regular sized archers and dwarf-sized archers) Hey, Robin, what are the little guys for?
Robin: I guess that's in case we duck.
Prince John: How are you going to do it? How are you going to get the gold?
Sheriff of Nottingham: Not to worry, my liege. My plan is not only flawless – it is foolproof.
Prince John: Yeah, but will it work? That's the main thing!
Prince John: (Receives a letter from King Richard) Well, how do we know it's from him, huh?
Sheriff of Nottingham: (starts reading letter) "My dear pea brain…"
Prince John: That's him! He's the only one who ever used to call me that.
Sheriff of Nottingham: A courier arrives, Your Highness.
Prince John: What do you mean, "Your Highness"? I'm not Your Highness! I'm a prince! My brother Richard is Your Highness – I am nothing!
Sheriff of Nottingham: As you wish – your nothingness.
Prince John: Right – huh?
