Back in the mid-to-late 90's when wrestling was popular my younger brother had a friend named Brandon who was a wrestling fan...Anyway Brandon told me if a wrestler had to go to pee during a match he'd pee in his pants.

I don't know if that's true or not but it sounds plausible, considering that the referee, probaby wouldn't stop a match on live tv just so one of the wrestlers could take a piss break.
