i liked frank because of all the stuff he put up with from hawk eye and the rest of the camp especially when he was left in charge all Winchester did was wine about being stuck at mash but he was pretty funny
I would have to agree with Greg. Major Burns was a big part of everything Hawkeye and the rest had to deal with. From him "trying" to be Army strict with everyone to his adultery with "Hot Lips". Him being the butt of most practical jokes helped make the show what it was. Having an uppity, spoiled Major Winchester just changed everyones storyline, but it definately worked too.
It was always funny as hell when they made fun of burns, but Frank got annoying. Charles ... I dont really know what to say about him but he thought he was better than everyone else. I cant really say.
