Little Johnny was staying with his Grandma for a few days while his parents were on vacation.
He had been playing outside in the street with the other local kids for a while, when he came into the house and asked her, “Grandma, what is that called when two people are sleeping in the same room and one is on top of the other?”
His Grandma was naturally a little taken aback at little Johnny’s question, but nevertheless decided to tell him the truth.
“It’s called sexual intercourse, darling”, she told him.
Little Johnny just said, “Oh, ok Grandma” and went back outside to go back and play with the other kids.
A few minutes later he came back in and said angrily, “Grandma, it is not called sexual intercourse! It’s called Bunk Beds!”
He then added, “Oh yes, Timmy’s Mom would like to talk to you”
