Once upon a time a long time ago, there once was a pink chocolate covered man. The color pink back then was considered a manly color(yup that is actually true). Wal anywhoo this pink chololate covered man often ate himself. He found that he was quite yummy but he didn't want to keep eating himself or else he would be dead(obviously). So he searched and searched the whole universe to find the source of his chocolateness. Along his way to find the chocolateness, he met an evil king named King Funny. King Funny was not funny. King Funny decided to kill the pink chocolate man because his kingdom, the source of the chocolateness, was running low on chocolate. So while awaiting his death, the pink chocolate man burped. King Funny yelled, "OFF WITH HIS LEGS!" and the pink chocolate man replied, "you can't say that for I no longer have legs!" and the pink chocolate man ate his legs and sighed. They were so yummy. King Funny yelled, "FINE! OFF WITH HIS HANDS!" and the pink chocolate man said, "nope! I have no hands!" and he ate his hands. They were also yummy. King Funny yelled, "FINE!OFF WITH HIS HEAD!" and the pink chocolate man didn't reply because he had already eaten his head. It too was yummy. All that was left of the pink chocolate man was his elbows because he couldn't lick it. King Funny said, "GIVE ME YOUR ELBOWS!" and the elbows came to him. King Funny liked them so much that he decided not to eat it and he named it after himself. He thought it was quite funny. That is how the Funny Bone came to be. burning_eyes
So basically, it's funny because King Funny, who was not funny, thought it was funny so there. xd I realized that I didn't really anwer the question!
