Pictures Are Naughty

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 you're mother calls your father".

"I know, I know," screamed Eddie. It's a horny bastard!"
