[Short story]Three guy go to cliff

There were a cowboy, an Indian and a stupid guy. They all went to this cliff that says if you jump off it and say something you will become it.

So the Indian jumped off and said fish! and he turned into a fish and fell into the lake below.

This cowboy jumped off and said eagle! and he turned into a eagle and flew away.

The stupid guy was about to jump but tripped and said, "CRAP!"
