Character history
Season three
Emmet does not like to have his face revealed on television, but composite images show that he looks similar to his brothers. Andy Richter shows up at the Bluth family's "Save Our Bluths" fundraiser dinner and chickens out of singing and dancing, claiming he is Emmett. ("S.O.B.s")
