I heard something on the radio while I was driving to work today that I didn't know. The original Greek Olympians competed in the nude, with the exception the chariot racers. After seeing this thread, I had to do a little research. One quote from the article I found was "Yes, that’s right – ancient Olympic sportsmen (all men, by the way) ran, wrestled, and fought buck naked." Please don't let this contest go that far.
