The Awesome Portal Song

So, I just finished Portal tonight and got a chance to hear what must be one of the funniest video game songs I've ever heard. Check out the link (minor spoilers) to view the end credits along with the awesome song "Still Alive". It's funniest if you've played the game and get the references (especially about Black Mesa - "Just kidding, ha ha, fat chance!").

Of course, if you like funny video game songs it's hard to beat this (2:45 in).
