Three men had been stuck on an island for ten years.

Just as they were about to give up hope, one of the men finds a magic lamp.

The first man wished to be 10% smarter, and then he was able to make a fire and send morse code smoke signals for help.

The second one wished to be 25% smarter, and suddenly he knew how to build a sturdy raft capable of getting them all off the island.

Then the third man wished to be 50% smarter, and he turned into a woman and walked across the bridge.
