I was watching the last episode of season 4 of House M.D. and it was interesting one. At one point in the show i was not sure what was reality or not, but what was really sad it what happen to him at the end of the show. He committed himself to a Psychiatric Hospital and they play the song As Tears Go By from the Rolling Stones. This is sad song about the person losing something..I do not know if it child or another person close to them. It was kind of fitting song for the last few minutes of the show because the person that Lisa Cuddy was not happy even though she was at a wedding and the person she was in-love with was getting committed to psychiatric hospital. You could see it on her face.
