There were 3 blondes stuck on an island in the middle of a river, which was too jump over and too rapid to swim to the sides. They find a genie in a bottle, who devides the three wishes between them, one each.

The first says "I wish I could swim like a fish". And she jumps into the river, but the current is still too strong and she is swept away to her death.

The second says "I wish I could fly like a bird", and she flies into the sky, but she goes so hight that she is hit by a plane and dies.

The third says "I wish I was a brunette" and walks across the bridge.
