Catchy :D
Call me sad, but I watched this five times and know all the words of by heart :P
I'd say it's the best tune I've ever heard in a flash movie, and definately the most catchy (or a close second to the annoying song, by weebl :P). The storyline is just plain wierd (a good thing, it's hilarious), and the lyrics are very well thought out, merging with the animation itself near flawlessly.
Though the animation isn't the best I've ever seen, the idea and background music is what does it for me. Great work :D
