You're going to watch the following "Ultimate Exercise Ball Fails Compilation" and say to yourself, "HAWW!! Stupid, stupid people." And yet I would be more inclined to say, "STUPID, STUPID EXERCISE BALL!" Why? Because in not a single one of these (okay, fine hilarious) clips does an exercise ball stay still and do what it was supposed to—that is to say, make the person jumping on it look super cool! Get with it, Exercise Balls! Stay still! AND STOP BEING SO STUPID!!
