Pinocchio and Splinters

One day Pinocchio came to Gepetto with a problem. "Every time I have sex with my girlfriend, she gets splinters. What can I do about this?"

"Have you tried sandpaper?" Pinocchio hadn't, so he went to try it.

"Pinnochio," said Gepetto a few weeks later, "How is the problem work out with your girlfriend?"

Said Pinnochio, "Who needs a girlfriend when you have sandpaper?"
