An episode featuring comedian/John F. Kennedy impersonator Vaughn Meader was produced in mid-November 1963, just about a week before President Kennedy's assassination. The segment never aired on NBC or in syndication. There are no reports confirming if prints of the segment were archived or destroyed.
On eleven season 3 episodes, the producer is credited as Josylar, which was Joey Bishop's production company. Josylar is an acronym of the first two letters of Joey's and wife Sylvia's first name and the first three letters of Larry Bishop, Joey and Sylvia's son.
