Sorry man.
I got the joke and all, and the joke alone was pretty good. It was the rest I had problems with. I can see you need a lil practice.
1) Try not to use that same annoying sound effect. I can imagine what it sounded like before it was supposedly more annoying. : )
2. Graphics. When you make a quickie, its got to be hella good looking, and hella funny. Practice your artwork, and the movie would look a lot cleaner
3) Animation is a staple point. It should be smooth without a doubt. In time, this will come naturally. For now, there is only practice.
Before you re-submit this if you do, I would suggest making little short animations. Not things to submit, but a stick throwing a baseball or some shit like that. It all adds up.
Good luck, but for now im sorry to say. BLAMMED.
