Little Johnny Again
 

A teacher in New York City wanted to see how many animals the city
kids in her fourth-grade class could identify.
She drew a picture of a cow on the blackboard and said, "Who can tell
me what this is?"
A little girl raised her hand.
... "Yes, Janie, what do you think it is?"
"It's a cow, teacher."
"Very good, Janie," said the teacher.
Then she drew a picture of a pig, and a little boy answered correctly.
She drew several other barnyard animals and was unable to stump the
class. Finally, she decided to try something a little more difficult.
She drew a stag with a large spread of antlers. The kids just stared,
but nobody offered an answer.
"I'll give you a hint," said the teacher. "What does your mommy call
your daddy when she's trying to be 'lovey-dovey'?"
Instantly, little Johnny raised his hand and said, "I know, Teacher.
It's a big horny bastard!"
