Katie was staying with her grandfather for a few days.

She had been playing outside with the other kids for a while when she came into the house and asked him, "Grandpa, what is that called when two people are sleeping in the same room and one is on top of the other?"

He was a little taken aback, but decided to tell her the truth.
"It's called sexual intercourse, dear."

Little Katie just said, "Oh, OK" and went back outside to talk and play
with the other kids. A few minutes later she came back in and said angrily, "Grandpa, it is not called sexual intercourse! It's called Bunk Beds!" " and Jimmy's Mom wants to talk to you"!!
