The rules of Birdman are simple. First, make the "okay" sign with your index fingers and thumbs. Rotate your wrists outward and flip these rings over your eyes. These are your "goggles." If, while wearing your goggles, you make eye contact with a participating Birdman player (after they've agreed to play with a handshake) he or she must immediately lie down so that his or her back touches the ground. However, should the targeted player sense your attack, he or she may block your goggles with the "monocle," or one index finger and thumb ring pressed against an eye with the other fingers pointing up. The origins of Birdman are shrouded in mystery. Suffice it to say the game is catching on in Tempe. Flash your goggles at the wait staff at Boulders on Broadway and prepare for the inevitable counterattack.
