There were three dumb blonde guys on an island who found an old pot and started rubbing at it, when suddenly out popped a genie. The genie told them that he only could grant 3 wishes so they would each get one.
The first guy asked the genie to make him smarter so he got turned into a red-head.
The second guy wanted to be even smarter than the first, so the genie turned him into a brunette.
Then the last guy wished to be even smarter than both his friends...
...so the genie turned him into a woman.
