Three fishermen were fishing when they came upon a mermaid, the mermaid offered them one wish each so the first fisherman said: "Double my IQ" so the mermaid did it and to his surprise he started reciting Shakespeare.
Then the second fisherman said: "Triple my IQ" and sure enough the mermaid did it and amazingly he started doing math problems he didn't know existed.
The third fisherman was so impressed he asked the mermaid to quadruple his IQ.
The mermaid said "Are you sure about this? It will change your whole life!" the fisherman excitingly said "Yes" so the mermaid turned him into a woman...
