Be Careful What You Trip Over

Three men die and are standing before the gates of heaven

The angel at the gates tells them that none of them were bad people, but not virtuous either.

Therefor, all he could offer them was reincarnation. But they could not reincarnate as people.

The angel points to a nearby cliff and tells them they can just run off the cliff and say the name of what they want to be reincarnated as.

One of the three says “I know exactly what I want to be!” and runs off the cliff yelling “Gorilla!”. And he becomes a newborn gorilla.

The next guy runs off the cliff and yells

“Eagle!”, and becomes a newborn eagle hatching from an egg.

The last guy thinks real hard about what he wants to be, and then takes off running.

And just as he runs to the end of the cliff, he accidentally trips and says “Crap!”.
