Also, since someone mentioned the Dr. McKay episode, I'd just like to say I was really disappointed with that one. When I heard that Dr. McKay was going to be on the show, my one & only hope was that he'd have some scenes with Dr. Rush. I was expecting his clashes with Dr. Rush to be even greater than his love-hate relationship with Samantha Carter or his brief fast-talking duels with Daniel Jackson. But instead, he & Rush never met each other once for the entire episode.
