"Dr. Katz" originally aired on Comedy Central from 1995-2002, and starred Katz as a professional therapist whose patients were chiefly other comedians and actors. He received a Primetime Emmy Award for his work on the show in 1995 for Outstanding Voice-Over Performance. He has also created the show "Raising Dad" in 2001. His voice can also be heard in the animated series "Home Movies", a show with many ties to "Dr. Katz", as well as on the Adult Swim animated comedy series "Squidbillies" where he performed uncredited voice-overs as "The Rapist" in Season 2 and as the Holodeck Therapist in Season 5.
