It's a joke that's funny because we can all relate to assholes like that but it certainly doesn't showcase his range. I'm sure anyone could have pulled off Lumbergh just as well. It's all in the writing.
That doesn't mean I don't like the guy he's done a lot of great stuff. Can we agree to pretend he never had anything to do with the Brady Bunch?
Aside from being that guy who shows up in stuff I'd be inclined to associate him with American Gothic or Harvey Birdman....or Crusade.
