This was a totally brilliant episode of house, the hallucinations really knock you off-guard. I'd say the best part of it would be either when House rips out his stitches and collapses in a pool of blood or when House gets the robot arm and drives it right through the patients abdomen and then nothing happens and you think "uh-oh, whats going to happen to him now?", then the bullet drops out of the patients hand and you go "phew". Hugh's acting in this episode is absolutely phenomenal and hilarious. After Cuddy and Wilson decide to give House Ketamine and he can walk it's very weird to see him do so. My favourite comment in this episode would have to be Cuddy: Stop dialling up your Morphine. That was funny
