The pressure's on, you need this half-strike to keep you in the game, so what do you do? You have yourself an incredible physics freakout, obviously. As with many of the greatest physics bugs, this looks almost intentional, like a super-special bowling move which involves a completely unnecessary ritual before sending the ball on its fateful journey down the lane. Once the dance is done, you know as soon as the bowl hits the ground that it's gonna damn well hit that pin.
