Abracadabra

A blonde, brunette, and a red are frolicking on the beach when the blonde suddenly trips over a bottle in the shape of a phallus.

Blonde: What is this? What do we do with it?

Red head: We're supposed to rub it silly!

So they huddle around the bottle and using both hands they all rubbed the bottle up and down ferociously.

Poof! A Genie squirts out of the bottle.

Genie: Thank you so much for that release. For that I shall grant you 3 wishes. You may each have 1 wish.

The Genie turns to the blonde: Tell me your wish and I shall make it happen.

Blonde thinks and tells the Genie: Well I've always wished I was smarter so my wish is to be smarter!

Genie: OK, Abracadabra!

And poof the blonde turns into a red head.

The original red head gets mad and turns to the Genie while pointing to the new red head and tells the Genie: I wish I was smarter than her!!

Genie: Alright, Abracadabra!

And poof the spicy red head turns into a brunette.

The original brunette is smart and sees everything that's going down.

Genie: Now tell me. What is your wish?

Brunette: I wish...I wish...I wish I was smarter than all 3 of us put together! Hah!

Genie: As you wish. Abracadabra!

And poof! The brunette turns into a man.
