Name one in-game situation in which spinning the ball on your finger would come in useful. Perhaps if you're counting on making the opposition laugh so hard they forget to guard you, but realistically it's a skill which has nothing to do with the sport of basketball at all. Despite this, just about every player will spend countless guilty hours perfecting this useless art - as well as other favourites such as rolling the ball around your arms in a circle, dribbling with your knees, and bouncing it between your legs as you walk slowly forward in a straight line. Master these and watch the admirers flock.
