A man walks into a bar and sits next to a guy with a little head. After having a couple drinks the man asks the other guy, "hey, I don't mean to be rude, but how is it you have such a small head."
The guy replies, "well it's a bitter sweet story. You see when I was in the war my plane got shot down in the Pacific. I parachuted out and ended up on an deserted island."
He continued, "after several months on this deserted island, a beautiful mermaid suddenly appeared and granted me three wishes."
"My first wish is that I'd like to be rescued from this island I told her."
To which the Mermaid said, "tomorrow a rescue boat will find you."
"My second wish is that I'd like to be rich for the rest of my days."
The Mermaid said, "invest early in these companies, and you will be a wealthy man...and what is your final wish?"
"Well Mermaid, you know I've been stranded on this island for so long, and seeing as you are so beautiful, I'd wish for nothing more than to sleep with you."
The Mermaid sighed and said, "I cannot grant you that wish, you see I'm a half fish, it would not work."
Frustrated, the man said, "Well how about a little head then?"
