Could have been better, but not bad.
While I have to say that the evidence which shows you used Windows Movie Maker is easily seen, this was better than what I thought it would have been (and trust me on this, most Flash made with Windows Movie Maker as an extra tool usually comes out looking absolutely horrible, unlike this). I think what really could have helped you is taking some more time to smooth the animation out, which you can do with Flash. It's actually much easier than doing frame-by-frame with WMM. Other than that, I would also recommend that you use a preloader for next time, as even though I had no problems loading a 7 megabyte Flash file to watch it, others undoubtedly will. But your choice of humor is wholesome, and it was worth a few chuckles. You get extra points for using audio from Yu-Gi-Oh the Abridged Series. :)
Animation: 5/10
Sound: 7/10
Humor: 8/10
Overall, not horrible, but could have been better. Keep going.
