H. Jon Benjamin
Character: A can of mixed vegetables (no, really)
Pre-WHAS: After starting out in experimental comedy in the early 1990s, Benjamin found his calling in animation, as a voice-actor and writer-producer. By 2001, his low, mumbly tone was already familiar to fans of Dr. Katz, Professional Therapist and Home Movies.
Post-WHAS: In between the occasional live-action performance — including in his Comedy Central series Jon Benjamin Has A Van — he's continued to be one of the most recognizable voices on TV. And as the leading man of Archer and Bob's Burgers, Benjamin's at the heart of two of the funniest adult cartoons of the past half-decade.
