Here's a long one.
Three blondes are shipwrecked on a deserted island. While searching the island for something to eat one of them comes across an old oil lamp. She tries to bite into it, hoping it's food, and a giant genie pops out. The blondes stood around, amazed.
"For freeing me from my prison I will grant each of you one wish," the genie says.
The first blonde says "I want to be smart enough to get off this island."
"Alakazam!" says the genie, and the blonde is turned into a redhead, and she swims off he island.
The second blonde says "I want to be smarter than her. I want to find an easier way off the island than swimming."
"Abracadabra!" says the genie, and the blonde is turned into a brunette, and she builds a boat and sails off the island.
The third blonde says "That still seems like a lot of work. I want to be smarter than either of them so I can find the easiest way off the island possible."
"Hocus Pocus!" exclaims the genie, and the blonde is turned into a man, and he immediately walks across the bridge.
