Charlie Oatway was once having sex with a tractor, when some of his sperm got into the cab. Nine months later, the tractor gave birth to Optimus Prime.
Upon hearing that his good friend Lance Armstrong lost his testicles to cancer, Charlie Oatway donated one of his to Lance. With just one of Charlie Oatway's nuts, Lance was able to win the Tour De France seven times. By the way, Charlie Oatway still has two testicles; either he was able to produce a new one simply by flexing, or he had three to begin with. No one knows for sure.
