We had this crazy guy once who was known as "The Sheet" because he would run into this mall I worked security at dressed in a white sheet like a ghost, squat down and take a dump right in the middle of the food court, and run away, escaping before security could nab him every time. We never caught the guy either, no idea what his deal was!

Some may call him a freak, but I say "That man was The Sheet!"

(Yes stolen joke... But funny.)
