A guy went into this bar and saw this man with a shrunken head. Amazed, he goes up to him and asks how it happened."I was a sailor who was shipwrecked on an deserted island" he replies. "When I was on the island, I saw this woman who looked like she was drowning, so I saved her. She turned out to be this beautiful enchanted mermaid and she offered me three wishes as payment. My first wish was to get off the island and back home. No sooner than I asked did we end up back at my house. My next wish was for money. The next thing you know, my house was filled with bills of all denominations. I couldn't have been happier. When she reminded me of my final wish, all I could think of was how beautiful she was. I wished to make love to her.She told me that it was impossible, seeing how she was a mermaid and all. So I said 'Well, how about a little head?'"
