The entry for calling shotgun on Wikipedia.  NOV 09 2006

The entry for calling shotgun on Wikipedia. There are almost 60 special amendments to the "official" rules, including "Amendment IX: Australian Shotgun. Originally from Australia, if two people tie for shotgun, then the first person to put their thumb on their head is awarded shotgun. If they both do this at the same time, then an immediate pissbolt (race) to the car is required." (via zach, who says "best Wikipedia entry ever?")
