In April 1969, CBS canceled The Smothers Brothers Comedy Hour (1967) owing to a conflict with Tom Smothers and Dick Smothers over what the two stars of the show perceived as unwarranted censorship by the network. Oliver mentions the cancellation as he vents his exasperation with the Pixley TV crew.
Haney sold the TV rights of the cannonball-firing ceremony to the Pixley TV station for $12.
The dog Lisa's " Mudder " brings with her is the same dog that was in the previous season's finale The Reincarnation of Eb (1969).
Lisa's mother never knows Oliver's name and calls him "Whatshisname". Soon, everyone in Hooterville is calling him that.
