I am curious to know how the Spurs pitched this idea of teaching fans how to properly towel-wave from the bench to Patty Mills. "Hey, so, you're the closest thing we have to a benchwarmer on this team. Would you like to mold the minds of future benchwarmers everywhere?"
(OK, so they probably just asked him to make an official version of this video. Still).
Luckily, Mills appears to be a good sport about it, so we all benefit.
