Duck Dodgers' disdain for the Martian Queen is due to the fact he is hidding a MASSIVE duck-boner to her.
Birds don't have penises, so he don't have to worry about the physical part of it, but he still act in desdain because he believes it would be the uncoolest thing to do to act his attraction to her out, like every else does.- MOST birds don't have penises... but ducks do.
