In one episode, Jerry becomes manager of a band known as The Warts. This was actually the band The Seeds, which recorded the classic single "Pushin' Too Hard".
The show was only moderately successful during its first season. NBC agreed to renew it on the condition that costs be held to the 1967 level, effectively freezing the talents' salaries. Producer Desi Arnaz obtained agreements from everyone on the cast and crew with the sole exception of Roger C. Carmel who held fast to a contractual point providing him with a raise upon renewal. Arnaz pleaded with him, pointing out that the livelihood of dozens of people were essentially at stake but he wouldn't budge, despite his then-decent $2,000 per week salary and the promise of residuals and was released. Carmel was replaced (by Richard Deacon) and the show sank miserably in the 1968 Neilsen's and was canceled. As a result, Carmel was effectively blackballed from the TV industry for several years.
The series was originally envisioned as a vehicle for Eve Arden and Ann Sothern until it was decided the two actresses' comedic styles were too similar and Sothern was replaced by the volcanic Kaye Ballard.
Roger C. Carmel, who played Roger C. Buell, was only three years older than Jerry Fogel, who played Buell's son Jerry.
Actress Kay Cole portrayed the "Suzie" character in the unaired pilot episode only. She was later replaced by Deborah Walley. In this pilot episode, scenes with Cole were later re-shot with Walley.
