Nice.
Okay, I know what the music was from, but I won't say since you're probably already tired of every single person saying: Hey, I know what songs you used! You used... and so on. Not that saying I won't say what songs you used is any quicker, but that's just how I am.
One thing I find funny is that the alternate ending had almost the exact scene I imagined was going to happen while watching the first ending. Both of them were funny, and the first one was expected, and yet extremely unexpected. The animation was very smooth, and this was overall a 4/5 from me. You've got to work a little harder to get a 5, but this was great, and I'd give you somewhere around a 4.25. Well, nice job, and good luck with that contest. ;)
