Cute.
It's funny, because it's true! Lol, I've seen those commercials, there so random, and it was actually pretty funny to see someone make a parody of them. I loved how he got shot about 7 times in the head and chest, and he died when the box hit him in the head.
But I'd suggest updating it a little, I'd really like a lipsync for the guy when he says "Are those fireworks?" Also, shading makes drawings have depth, which is important in cartoons, so I'd suggest shading. But thats about it.
