I, too, liked this.
I thought it was actually quite silly, and I commend the for that. I do think that you need to work on trimming your sprites, I thought that that excess stuff you had around the Wario sprite when he was doing various gestures lowered your flash's classyness just enough so that some people will problem think it not worthy enough to stick around to watch it in its entirety. Otherwise, I hope you keep up the flash-making, because I look forward to your next efforts.
You got a 4/5 (since it's the oh holiest of days, clock day!)
