Kobe Bryant is a merciless competitor. Take, for instance, the very strange charity game Bryant played in Shanghai over the weekend. The game was filled with Chinese pop stars, and the format was two 15-minute halves with running clocks. Bryant sat out the first half and his team fell behind. He got the deficit down to nine before fans texted the opposing team 20 points (yes, really).
Black Mamba then went off, finishing with a self-reported 68 points in 15 minutes. If you want an indication of how seriously Bryant took the game, watch around the 44-second mark when Bryant hounds a slight woman who can barely dribble, steals the ball, then throws down a thunderous dunk. [Source]
