Up next on my tv is Mash.
Early episode but not too early, Frank is gone but Radar is still there; klinger is still wearing dresses which didn't change till have way through the shows run.
I have to say, I prefer the shows after Frank left... I found him to not just be as annoying as he was supposed to be... he was annoying as a character as well. Played out by the end of the first season.
