Jimmy goes into a bar after a hard days night. He sits at the first stool at the end near the door and orders a drink. He looks around at the place and thinks "pretty typical"...then he notices, at the other end of the bar, a guy with a really small head.

He stops the bartender and inquires "What's with that guy?" The bartender replies "Go buy him a drink and he'll tell you". Jimmy gets up and walks to the other end of the bar and sits down next to man with the small head. "Can I buy you a drink" Jimmy asks, and the man with the small head replies in the highest pitch voice Jimmy has ever heard... "Sure!!!". Jimmy orders them both a drink, and asks "So, what happened to you?"

The man with the small head answers (with that same high pitched voice) "Well...ya see... I was stranded on a desert island, and I met this mermaid, and she granted me one wish... so I thought for a little while and then I said "OK... how about a little head?".
