The first-grade class gathered around the teacher for a game of “Guess the Animal.” The first picture the teacher held up was of a cat. “Okay, boys and girls,” she said brightly, “can anyone tell me what this is?” “I know, I know, it’s a cat!” yelled a little boy. “Very good, Eddie. Now, who knows what this animal is called?” “That’s a dog!” piped up the same little boy. “Right, again. And what about this animal?” she asked, holding up a picture of a deer. Silence fell over the class. After a minute or two, the teacher said, “I’ll give you a hint, children… it’s something your mother calls your father.” “I know, I know,” screamed Eddie. “It’s a horny bastard!”
