Great, now I've
got the "Single Female Lawyer" song stuck in my head.
I love M*A*S*H
(never mind that it ended two years before I was born) but Hawkeye is one of my least favorite characters. He used to be my favorite, but the more I've watched the show, I've come to realize that I like Klinger, Potter, Winchester, Radar, and Mulcahy a lot more. I guess eleven years' worth of episodes is just too much Hawkeye for me.
As far as Star Trek series go, I'd have to say Sisko is my least favorite character on DS9. It's not that I dislike him; I'm just kind of... indifferent toward him. He had some good moments, but I'd rather watch an episode that focused on, well, any other character.
