One Wish Each

Three blondes were walking through the desert when they found a magic genie's lamp.

After rubbing the lamp to make the genie appear, he said:

- I will grant three wishes, one for each of you.

The first said:

- I wish I were smarter.

So, she became a redhead.

The second blonde said:

- I wish I were smarter than she is.

She became a brunette.

The third blond ordered:

- I wish I were smarter than both of them!

So, she became a man.
