THE BIRDS AND BEES TALK
A young girl unexpectedly walks in on her parents having sex, Mum on top. After surveying the scene for a moment or two, she asks what they are doing.
“I was just letting some of the air out of Dad because he’s too fat,” said Mum.
The girl replies, “What’s the point? The lady next door is just going to blow him up again tomorrow like she usually does.”
