At the beginning of the 1963–64 season, Desi Arnaz resigned as head of Desilu and as the executive producer of "The Lucy Show". Ball took over as president of the studio and Elliott Lewis replaced Arnaz as executive producer of Ball's series. Dick Martin, Don Briggs, Tom Lowell, and Charles Lane left the show. The characters of Harry Connors and Alan Harper were never mentioned again. Briggs would make one more appearance as Eddie Collins in the episode "Lucy Goes Duck Hunting". The Barnsdahl character was replaced by Theodore J. Mooney, played by Gale Gordon, who would remain with the series for the remainder of its run, surviving another format change. In the episode "Lucy Gets Locked in the Vault", Gordon's character is introduced when Lucy discovers that Mr. Barnsdahl has been transferred to another bank and that the management of her trust fund has been taken over by a new banker. The name "Theodore Mooney" had been used earlier by the actor George Cisar, who was cast as a police sergeant on thirty-one episodes of Gordon's other CBS sitcom, "Dennis the Menace".
