What a great show. I recommend watching the whole thing. Fun fact: MASH was not aired in chronological order! If you watch the episodes in the order they aired (which is the standard order), you'll notice weird little things like the season changing from episode to episode. There's also one season in which they invent a vein clamp, so in addition to the episode where they actually come up with it there's an episode where they show them to another military hospital as well as at least one other episode where they reference the clamp. Well as you might have guessed by now, the network aired the other episodes involving the clamp before they actually invented it. The way episodic TV was at the time everything was usually back to normal by the end of the show, so this was apparently a pretty standard practice.
