"The foolish leader, the two normal people who realize how foolish the leader is but are inhibited from saying so, and the creepy suck-up."

A template for fictional characters proposed by my son John in an iChat discussion about "Flight of the Conchords":

When I first saw the show, I felt like, "well, I'm not that interested in the two main characters, so I probably won't like the show very much."... It's weird for those 2 characters to be so central, yet I see almost no differentiation between them. In any given episode, Brett might be acting differently from Jemaine. But it doesn't seem to be part of any larger character trait — "oh, that's so Brett!"

I said: "sometimes having a bland center works as a plot device. i learned that when I studied 'tom jones' in high school." John said:

[Brett and Jemaine are] kind of like Jim and Pam on The Office. And Michael Scott is like Murray. And Mel is a lot like Dwight. Those 4 fit the same basic template.

So there's the more general idea of the dull central character (or characters) and the more specific idea of 2 bland central characters with 2 livelier characters, one of whom is the foolish leader and the other who's some kind of weird suck-up. Examples?
