The Mermaid

One day three men are out having a relaxing day fishing, when suddenly
they catch a mermaid. After hauling the mermaid up in a net, she
promises that if the men set her free, in return she will grant
each of them a wish.

The first man doesn't believe it so he says, "Alright, if you can really
grant wishes, then double my IQ."

The mermaid says, "Done" and suddenly, the first man starts to
flawlessly recite Shakespeare and analyze it with extreme insight.

The second man is so amazed, he looks at the mermaid and says, "Triple
my IQ."

The mermaid says, "Done" and the second man starts to recite solutions
to all of the mathematical problems that have been stumping all of the
scientists in various fields from physics to chemistry, etc.

The third man is so enthralled with the changes in his friends, 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 man responds, "Nope, I want you to increase my IQ times five, and
if you don't do it, I won't set you free."

"Please," said the mermaid "You don't know what you're asking...it'll
change your entire view on the universe. Won't you ask forsomething
else... a million dollars, anything?"

But no matter what the mermaid said, the third man insisted on having
his IQ increased by five times it's usual power.

So the mermaid finally relented and said, "Done."

The third man became a woman.
