No pen license?!
Haha, man, this kind of stuff usually doesn't get me so much, but I've ended up watching this a dozen times over the course of the day.
I think the thing that really does it for me is actually the body language. It adds so much extra effect to everything and it's an area I find a lot of flash movies lack and they either have very minimal or it just looks really stiff. Like the kid's arm when he's explaining he doesn't have a license and the teacher's head tilt on "No license?".
The build up music worked well, but you stopped it too many times. When you stop it, it cuts off the build up then it has to rise again. Doing it can be good for comedic effect or shock or something, but you did it too many times, too quickly and seemingly without much reason. Not a huge point, but something you can very easily improve on in the future.
Also, the little drum thing for the title seemed a bit too random. It sort of seems like it's going to go into a song, but you're not sure what it's really there for. It'd be better if it was a few notes on an instrument instead.
Congrats on front page. And btw, I loved you ignite people on fire series :)
