This is from a comedian on A&E's "Evening at the Improv":
Have you ever tried to tickle yourself? Everybody has some whacko aunt or uncle that can just point at you and have you rolling with laughter. But if you shove your fist in your underarm for a week and a half you won't laugh. Somehow your underarm just knows that it's your fist. Thank God other parts of our bodies are dumber.
