愚人笑话|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^1!
