If everyone was nice, life would get pretty boring, wouldn't it? The television landscape is full of characters who made shows more interesting by doing what they do best: annoying the living hell out of everyone else. There's a lot to choose from, so share some of your favorites in the comments. Below are some of my personal faves:

Major Frank Burns: Alan Alda gets a lot of credit for his acting chops and his portrayal of Hawkeye on M*A*S*H, but Larry Linville deserves just as much, if not more, credit for his role as Frank Burns during the show's early years. Yes, he was a jerk, and yes, he was self-centered and only cared about doing what was in his best interest, but beneath it all was a very real vulnerability, a man who still held on to the childhood notion that the world owed him something. Maintaining that balance is not easy, but Linville did it perfectly.
