Grandmas Don't Know Everything

The little boy was playing outside with the other kids for a while when he
came into the house and asked, 'Grandma, what's that thing 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 just tell him the truth.
'It's called sexual intercourse, darling'

Little Jake just 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 sexual intercourse. It's called Bunk Beds. And Jimmy's mom
wants to talk to you.'
