The script for this episode launched the writing and producing careers of co-authors Bill Persky and Sam Denoff, who submitted a draft "on spec" to series producer Carl Reiner. Reiner eventually hired them as story consultants to take on part of the writing duties that he had theretofore carried mostly by himself. Persky and Denoff would ultimately contribute nearly 30 co-written scripts for the show, and would even take over Reiner's role as producer while he was filming The Russians Are Coming the Russians Are Coming (1966) during the show's final season.
