The Flintstones and the Rubbles are fans of “Peek-a-boo Camera,” a show that catches people off their guard as they go about daily life. Fred and Barney are invited to a bachelor party thrown by the Water Buffaloes. The boys lie to their wives that they are going to visit a brother Buffalo in the hospital, then attend the party instead–and are filmed there by the crew of “Peek-a-boo Camera.”
