Steve Higgins
It's fairly common for comedians to move into behind-the-scenes roles as writers and/or producers after their onstage careers peter out. In the case of Steve Higgins, his transition from a sketch comedy performer (as one-third of The Higgins Boys and Gruber) to a high-level role at "Saturday Night Live" was in keeping with that trend, but his subsequent side job as the announcer and sidekick on "Late Night With Jimmy Fallon" was more unexpected.
