Dr. House House M.D. characters' daemons (explained in the description).
If you've read His Dark Materials, or watched The Golden Compass (a lame attempt at representing the awesome book, but that's kinda off topic), you'll know what daemons are.
If you haven't, though, a daemon is basically an animal representing a person's soul (in fact it's part of their soul) and in most cases, it's always with them. So the point of this forum is... What animal do you think the daemon of each House M.D. would be?
