EDIT:i saw an episode where this guy is looking for his friends in the cafeteria but all he recgonizes is the back of their head and when he comes to greet them its someone else, amusing :D
Ah - Scrubs..... possible my all-time favourite comedy-show.
I especially love Cox and the Janitor. Each one of them on his own is already great, but when they're united on-screen, everything they touch turns into gold.
