One night, Pinnochio's girlfriend says to him, "This stinks. Every time we make love I get splinters."

So Pinnochio goes to Gepetto to ask his advice.  Gepetto says,

"Sandpaper, my boy, that's all you need."

A few days later Gepetto runs into Pinnochio and says, "So

how are you doing with the girls now?"

 

Pinnochio says, "Who needs girls?"
