Teacher is showing pictures of animals to her kindergarten students, and asking them to name the animals. "Ant", "Bear", and "Cat" are no problem, but when she shows a picture of a white-tailed buck, the class is silent.
"Come on," she coaxes, "I'll give you guys a hint. This is what mommy sometimes calls daddy when he hugs and kisses her a lot."
"I know!" cries little Mary. "It's a horny bastard!"
