#416. When one brother leaves the company and returns a few years later, you are no longer brothers. Just best friends. (Edge & Christian)
#417. You have the best chance of winning the Royal Rumble if you draw #27, not #30.
*#418. When competing in a cage match, no competitor shall be physically able to climb the cage at any speed faster than 1/8th their normal speed.
*#419. When competing in a battle royal or Royal Rumble match, wrestlers will become heavy as stone to prevent being tossed over the top rope.
*#420. In a heel vs. babyface tag team match, there must be at least one part of the match where the babyface who is not the legal man must suddenly distract the referee for reasons not fully understood or warranted, leaving his partner vulnerable to the inevitable heel double team far from the referee’s prying eyes.
*#421. Once a wrestler denotes a maneuver as his “finishing move,” the ability becomes devastating and impossible to recover from (unless one or two of the following conditions are met: 1. match is taking place at WrestleMania, 2. opponent is John Cena) if and only if the move is performed by said wrestler, or his opponent in a mocking manner.
*#422. When competing in an Iron Man match, two out of three falls match, an elimination tag match, or a similar endurance-based altercation, normal maneuvers take a noticeably increased toll on the wrestler, allowing pinfalls and submissions in situations and timeframes where they would otherwise not be possible.
*#423. It is acceptable to reverse moves in illogical, physically impractical ways as long as absolutely everybody believes in its legitimacy, including your opponent, the referee, and the commentators.
*#424. A wrestler may denote one to three objects as his “signature weapons,” which must be kept in the ringside area at all times during his matches. It is the responsibility of the ring crew to make sure this weapon is readily available.
