9. Bill Murray Co-Invented Shotgun Golf
Playing off a highly-respectable handicap of 7, The Caddyshack star certainly knows his way around the sport and is regularly seen participating in celebrity tournaments. He, along with good buddy and fellow sycophant despiser, Hunter S Thompson, are the co-founders of the extremely left-field sport that is Shotgun Golf. The game itself is rather Ronsealesque. One participant aims to pitch the ball onto the green from the tee whilst the other is bequeathed with the task of obliterating the opponent's ball, mid-flight, with the aforementioned shotgun. Sounds like an entirely safe post-boozy breakfast activity for two hot-headed former drug dabblers, wouldn't you think? Nevertheless, how many sports have you created, eh? And let's not kid ourselves, it'd be a darn sight more entertaining than half of the no-mark spectator sports that the London folk were lumbered with during the Olympics. Greco-Roman wrestling? Don't get me wrong, I'm sure that lot could all too easily remove my right arm from its birthplace of the shoulder and club me to death with it. But that's not the point, watching it is about as pleasurable as pleurisy.
