Well, your line-work is clean, coloring's nice, animation is smooth. I also liked the background at the beginning part.
But the animation was just so incredibly stiff. One thing I think you need to learn, along with so many other animators out there, is that smooth alone does not equal good animation. There's also laws of motion and bouncing, squeezing and thrusting. FORCE behind movements that become initiated. Some people do this but just do it wrong, like put too much force behind a very small movement or vice versa, but you don't seem to do it it all. Of course these do not always need to be over-exaggerated if that's not the style you're going for, but you should have them nonetheless, considering that that is just how physics works. With this, especially at the last part, the guy who threw the chair and stuff... it just didn't look good, it was smooth, but it just didn't make sense, he sorta like slowly transitioned to certain positions, rotated and slowly moved his arms to throw the objects.
This is an issue I see often, and to the untrained eye it may look "good" simply because there's a lot of frames, but there was no style, it's just so basic. I mean anyone who spends a bit of time animating could pull off that sequence. Animators should have their own specific animation style.
What really killed it for me was just the length of the video itself (not really any longer than 10 seconds), and the joke was so stock, I mean you could've replaced this with any game and there'd be no difference, all online games have errors. Just random screaming and freaking out with that same overused abrupt ending every single person is doing now just doesn't make ME laugh, at least.
You make videos very, VERY fast... you need to spend more time on a single one. Quality over quantity. But... thanks to your constant awards, front-pages and high scores, maybe none of this criticism even matters. I mean why should it, right... you don't even have to try and it's almost for-sure that your video will get super popular.
