Pinocchio has just turned 16 years old and Geppetto thinks to himself: "Just now my son is going to take an interest in girls, I had better explain to him about the birds and the bees."

So he spends time telling Pinocchio about girls and making love. Pinocchio listens intently and then goes off to experiment.

Some time later, Geppetto sees his son and asks, "How's it going with the girls?"

Pinocchio replies, "Great, I'm doing fine, except that all the girls are complaining about splinters."

"Oh dear," says his father, "All I can suggest is that you smooth things over first with some sandpaper."

Some time later he sees his son and asks, "How's it going with the girls?"

"Who needs girls when you've got sandpaper?!?"
