Tiny Headed Man

A guy with a very small head was sitting at a bar, drinking, when the bartender asked him why his head was so small. The man sighed.
"I was walking along the beach one day and happened upon a lamp. A beautiful genie came out of the lamp and said that she would grant me 3 wishes. First, I wished for all the money in the world. Then I wished for the biggest mansion in all the world."

"Yeah?"

"And then I wished for a little head."
