Three guys are out having a relaxing day fishing. Out of the blue, they catch a mermaid who begs to be set free in return for granting each of them a wish. Now one of the guys just doesn't believe it, and says: "OK, if you can really grant wishes, then double my IQ." The mermaid says: "Done". Suddenly, the guy starts reciting Shakespeare flawlessly and analyzing it with extreme insight. The second guy is so amazed, he says to the mermaid: "Triple my IQ". The mermaid says: "Done". The guy starts to spout out all the mathematical solutions to problems that have been stumping all the scientists in various fields: physics, chemistry, etc. . . . The last guy is so amazed with the changes in his friends that he says to the mermaid: "Quintuple my IQ". The mermaid looks at him and says: "You know, I normally don't try to change people's minds when they make a wish, but I really wish you'd reconsider". The guy says: "No, I want you to increase my IQ five times, and if you don't do it, I won't set you free. "Please," says the mermaid. "You don't know what you're asking, it will change your entire view on the universe. Won't you ask for something else... a million dollars, anything?" But no matter what the mermaid said, the guy insisted on having his IQ increased by five times its usual power. So the mermaid sighed and said: "Done". And he became a woman.
