As ridiculous as it sounds, sometimes people who suck at sports feel the need to make up their own -- I assume this is how dodgeball got started -- or they took to heart the child acronym K.I.S.S. (keep is simple stupid) when inventing this new sport.

Here are the rules:
1. Don't break your tube. In a duel, the last person with an unbroken tube is declared the winner.
2. No stabbing. Lunges involving tubes are never allowed under any circumstances.
3. Try not to work the face. Hitting people in the face is heavily frowned upon and can force your ejection from the event.
4. Once your tube is broken you must stop fighting.
5. You may not block your opponents tube with your arms, hands or legs.

Actually, despite appearances and adult-like anticipations, this is a highly disciplined, well, maybe not highly, but at least somewhat disciplined play battle ... aka the opportunity to whack the daylights out of another adult and not get into trouble.

I wonder if pillow fighting will ever catch on?
