Trapper John? Hawkeye Pierce? Those two were the duo in the first three series. But I prefer Hawkeye and BJ. Henry was the incompetent CO/ great surgeon/swell guy who died in the episode "Abyssina Henry" (did I spell that right), at the end of Season 3 - the second best episode; the best episode was the series finale "Goodbye, Farewell and Amen."
I can't remember when, but I found this online quiz on the internet (for fun purposes of course) which tells which M*A*S*H character that I am most like. It said that I resemble Margaret Houlihan - who was better known as 'Hot Lips', until Season 5, when she became a more round character after her marriage to the jerk Lt. Colonel Donald Penobscott.
Like most people, Radar was the best company clerk in the series - even though Klinger eventually got a hang of it when Radar went Stateside after his Uncle Ed past away. I love both Radar and Klinger.
The only character that I hate is Major Frank Burns. I was a good thing that he went insane after Margaret's wedding (good riddance) - he was transfered stateside with a promotion to Lt. Colonel!!!!!
I prefer Potter to Henry, because he was a better CO.
Charles was very arrogant, but he was a WAY nicer second-in-command than Frank ever was; I don't think Frank ever had any true friends at the 4077th - Margaret dumped him in Season 4 the second she met her future-ex-husband Donald in Tokyo and was engaged shortly after. Margaret seemed to find a better man while she was engaged - but like Hawkeye and the others discovered in Season 5, Donald pulled a "Frank Burns" and was cheating on Margaret while she was working at the 4077th. I was just as happy as Margaret was when she got her divorce with alimony in the episode "Hot Lips Is Back In Town,"; that episode is my third favourite because of Radar's side storyline when he falls in LOVE - so desperately and the new nurse who he has so much in common with feels the same way. Gotta love Radar, so adorable - in a 'cute' sense.
