Life isn't easy when you're a disembodied head without skin.
The trials and tribulations of a superhero kid and his evil twin.
How much fun can one have with dead babies?
When you beat Portal you're treated to this song. It's called "Still Alive" by Jonathan Coulton (http://www.jonathancoult on.com/). Loved it so much I made it into a video. Enjoy!
