A man kills a deer and takes it home to cook for dinner. Both he and his wife decide that they won't tell the kids what kind of meat it is, but will give them a clue and let them guess. The kids were eager to know what the meat was on their plates, so they begged their dad for the clue.
Well, he said, "It's what mommy calls me sometimes".
The little girl screams to her brother "Don't eat it, it's an asshole."
