A long time ago there was a very wealthy king who unfortunately had a tiny head. One day a brave servant approached the king and asked about his little head, to which the king replied.
"Well, I used to be a ordinary citizen like you. One day I was walking along the beach and came across a trapped mermaid. As compensation for freeing her she granted me 3 wishes. I of course wanted power and wished to be a king, I wanted riches, and wished for money, it was done. Then I wished for the beautiful mermaid to have sex with me, to which she responded but I cant I'm fish from the waist down. To which I responded, well could you give me a little head then."
