Three blondes are stuck on a desert island...

Three blonde women are stuck on a desert island when they find a magical lamp with a genie inside.

I have three wishes to offer, says the genie, so that makes it one wish for each of you.

I want to be smart enough to get off this island, says the first blonde. She becomes a redhead, builds a small raft and sails off the island.

I want to be even smarter than her, says the second blonde. She becomes a brunette, builds a comfortable sailing boat, and sails off the island.

I want to be the smartest, says the third blonde. She becomes a man and crosses the bridge.
