Which of these people never appeared on The Dick Van Dyke Show?

Garry Marshall (who was also one of the show's writers) appeared twice: as a boxing referee and as a bartender in an Old West saloon. Legendary insult comic Don Rickles played an elevator operator named Lyle Francis Delp, while Gavin MacLeod (The Love Boat's Captain Stubing) once appeared as Mel's cousin Maxwell Cooley, a wholesale jeweler.
