Billy was over at Grandma's house to visit, and as usual, got together with some of the other kids in the neighborhood to play. Some of them were older then Billy, but Grandma kept an eye on them and only worried a little.
About lunch time Billy came in for a quick bite to eat and asked Grandma a question. "What do you call it when two people sleep together in the same room, you know, one on top of the other, all night?"
Grandma stuttered and stumbled over that one and finally came out with, "Do you mean "intercourse"?" "I guess so," Billy answered. He finished his lunch and left.
Grandma worried about this alot and noticed Billy coming back pretty quickly from his friends house.
"Grandma, that word I asked about is "bunkbed", and Jimmy's mom wants to have a word with you."
The best things in life, are not things.
