The change that always intrigues me is that Frank Burns character.

In the original book and movie [he was played by Robert Duval] Frank is not an idiot. He's a competent surgeon. The reason the others hate him is that when a patient lives it's because Frank is a great doctor, and when a patient dies it's someone else's fault. Trapper punches him after Frank tells an 18 year old corpsman that the corpsman had killed a patient.

Winchester was overbearing and obnoxious, but he had a sense of humor and a modicum of self-awareness.

Thank you for bringing up the term "bottle episode" again. I was trying to remember what it was called and searching was only coming up with clip episode.

Someone posted a picture of an episode of Frasier at the spa "There is a platinum door?" and I was wanting to see if that matched the bottle episode definition.
