Why was this front paged?
Tweeny animation is tweeny. I'm not saying I'm a better animator than you, so don't get me wrong, but you need more frame by frame. Plus, you made the guy grab his friend's balls?! What the hell? What kind of vibe is that supposed to give off? You could have left it at "I can't feel my balls," But no. Not you, being the comical genius you are. You had to make him reach down, and grab his friends balls.
Not only was the animation tweeny, but the voice acting was very... average. Not very good. At all. I would suggest finding new VA's. Not only that but the idea for the episode has been used so many times before. Guy pisses bully at school off and has to fight him, very original. The only difference is that anyone but you could pull the idea off.
The jokes were stale, to say the least. Stating the obvious constantly doesn't usually make for good humor and slapstick isn't funny if you can't pull it off. I'd consider having a co-writer or something that has funny material.
Don't pull the "OH, you're just mad because you can't get views" thing either. I don't expect views, I'm new to Newgrounds and only have one animation up.
Nice attempt, but overall, I just don't think it's worth the front page space.
