The 40 Best Guest Stars on The Office, Ranked

Do you recognize all of these stars from the hit sitcom?

1 of 37 NBCUniversal

40. Idris Elba (Charles Miner)

The Office is known for its eccentric and hilarious characters and its bevy of classic cameos. These are the 40 best cameos from the sitcom, ranked by a highly scientific algorithm measuring the combination of hilarity and likability.

Don't get us wrong: Elba is great in his part as Michael Scott's new boss, Charles Miner. But the former Wire actor's character is supposed to be unlikeable. He succeeded, so he's ranked low.

Elba, who debuted in "New Boss," appeared in seven episodes throughout the show.
