Sorry I had to make a thread about this. If anyone here has played Portal off of Orange Box and beaten it, you know how awesome this song is. http://www.youtube.com/watch?v=RthZgszykLs&mode=related&search=
Yes, it was AWESOME. The game was hilarious because of the commentary. The achievement for getting bronzes, silvers and golds on all levels and modes is insane.
I love this song. I like quite a few songs from Jonathan Coulton. His cover of Baby Got Back is funny. EDIT: Also I'm so getting The Orange Box next week.
