8. Kenan Thompson
Very few SNL cast members can say that they’ve been doing televised sketch comedy as long as Kenan Thompson has. He joined the cast of All That when he was 16 and then had a hit show with Kenan & Kel after that. The man is a true veteran. The only problem he has is that sometimes he doesn’t convince us that he’s playing someone else (he uses the same cadence for almost everyone he portrays), but he’s always funny anyways. And that’s what counts.
