One day Pinocchio came to Geppetto 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. "Pinocchio" said Geppetto a few weeks later. "How is the problem work out with your "Girlfriend?" said Pinocchio. "Who needs a girlfriend when you have sandpaper?"
