In a rare game show appearance, Peppard did a week of shows on "Password Plus" in 1979, in which he could often be seen smoking cigarettes while filming. Out of five shows, the first was never broadcast on NBC, but aired much later on GSN and Buzzr, because of on-camera comments made by Peppard regarding personal dissatisfaction he felt related to his treatment by the NBC officials who supervised the production of "Password Plus". As a result of this, Goodson-Todman banned Peppard from appearing on any of their game shows ever again for that incident, which cost them a lot since they had to film an extra episode two weeks later to make up for the pulled episode.
