Three Guys and a Genie

There were three guys stuck on an island. On of them found a lamp and rubbed it. Out came a genie. He said for freeing me I'll grant you each a wish. The first guy said I wish I were 25% smarter. So poof! He was 25% smater built a raft and got off the island.

The nex guy said I wish I were 50% smarter. So poof! He was 50% smater built a canoe and got off the island.

The last guy said I wish I were 100% smarter. So poof! He was 100% turned into a girl and walked across the bridge!!
