Little Tony was 7 years old and was staying with his grandmother for a few days. He’d been playing outside with the other kids for a while when he came into the house and asked her :

‘Grandma, what’s that called when two people sleep in the same room and one is on top of the other?’ She was a little taken aback, but she decided to tell him the truth. ‘It’s called sex, darling.’

Little Tony said, ‘Oh, OK,’ and went back outside to play with the other kids.

A few minutes later he came back in and said angrily,

‘Grandma, it isn’t called sex. It’s called Bunk Beds. And Jimmy’s mom wants to talk to you.’
