[Prodigal Son]

If you find that you have slipped off a tall building accidently and are plummeting earthward at alarming tempo- spread your arms and repeat to yourself over and over with total conviction- "I can fly, I can fly!"

It can't hurt.

[Chewbacca]

Too bad a naked woman didn't jump out of the bushes at the last second to distract the man while falling. He might have missed the ground and learned to fly.

At least that is what Arthur Dent taught me when reading Hitchhikers Guide to the Galaxy.
