Did Tony really mess up Bruce's bowling game on accident? The way Tony swings his fist afterward made me think he did it on purpose, as did the fact that the ball nearly hit a strike before he interfered.
To me it looked more like a "dang, that wasn't how that was supposed to turn out" swing. A triumphant swing is more up-to-down rather than right-to-left. It fits in with the previous gag where his suit calculated the exact angles he should throw the ball at, only for him to hit only one pin. He's just really bad at aiming.
Does it seem worth noting all the YouTube commenters who thought Tony did it on purpose?
