From 1992 to 1998, he participated on CBS's "Beakman's World". In it, Ritts starred as Lester, a disgruntled actor (with a bad agent) in a rat suit who reluctantly helps Beakman with his experiments and trades barbs with Josie, Liza and Phoebe. The character was originally conceived as a puppet character, but at the last minute, the show's producers decided he would be a costumed actor. Ritts also operated the Herb penguin puppet, with the voice provided by Alan Barzman. The program has been televised in nearly 90 countries around the world, and is seen in syndication throughout the United States.
