"OK, double my IQ", says the FIRST Fisherman. "Done," says the
mermaid, as the man, to his amazement, begins to recite Shakespeare.
The SECOND Fisherman is so staggered he says to the mermaid, "Triple my IQ."
"Done," says the mermaid, as he spouts solutions to math problems he never
knew existed.
The THIRD Fisherman is beside himself. "Quintuple my IQ!", he
screams. The mermaid looks at him and says, "Normally, I don't
try to change people's minds when they ask me for a wish, but I'd really
like you to reconsider."
"No, I want my IQ increased five times, and
if you don't, I won't set you free."
"Please," says the mermaid.
"It will change your entire view of the universe." But no matter what
the mermaid says, the third fisherman persists. So the mermaid sighs
and says, "Done."
And with that, he became a woman.
Three guys are out fishing, when one catches a mermaid. She offers
to grant each fisherman a wish in exchange for her freedom.
