Joke Over was recorded in the studio on 29 and 30 May 1975. The location footage was filmed near Middle Wallop in Andover, Hampshire on 21 May 1975. The scavenger hunt plotline was inspired by the autobiography of Barbara Cartland, We Danced All Night. This had also been used by Rosemary Anne Sisson in the earlier episode Laugh a Little Louder Please. In Joke Over, Madeleine Cannon makes her final appearance as Lady Dolly Hale.
