A sailor walks into a bar. The bartender immediately notices that this
   is a pretty well built
   guy but he has the tiniest little pinhead. After serving the sailor a
   couple of drinks,
   curiosity finally gets the best of the bartender and he asks the
   sailor why he had a normal
   sized body with such a tiny head. The sailor tells him this story: "I
   was involved in a naval
   battle where I was the only survivor. I was stranded on a deserted
   island in the middle of
   the ocean for months, when I happened across a mermaid while I was
   walking on the
   beach." She was on the beach and couldn't get back in the water so I
   helped her get back
   to the ocean, she was so grateful she granted me three wishes. I first
   asked to be rescued
   off that god forsaken island. She told me that it was no problem, that
   the rescue ship was
   on the way, and that I still had two more wishes." "Next I asked for a
   never ending roll of
   twenty dollar bills." Then the sailor reached into his pocket and kept
   pulling out 20s and
   putting them on the bar. "Finally I said to her, 'I've been on this
   island for quite some time
   without a woman and I'm quite horny, She said "as you can see from the
   waist down I'm a
   fish so I'm sorry but I can't help you there." "Well I thought about
   it for a minute and said
   OK, how about a little head.
