M*A*S*H (1972-1983)

I loved the character of Charles Emerson Winchester.
Unlike the cartoonish Frank Burns, Charles was a three-dimensional character who evolved during his time on the show.
I remember a late episode when Charles and Hawkeye were expressing mutual admiration for their fathers; it was a bonding moment, and it ended with the two men shaking hands.

In the record-breaking farewell episode, Charles taught some North Korean POW's to play music.
Later, when those soldiers were killed, Charles vowed to give up music, which was his passion.
I hope that vow was short-lived, and that he found a prodigy in the US who would rekindle that passion.
