The plot of this very brief pilot would be used and expanded upon in one of the early Flintstones episodes, "The Swimming Pool." Fred Flagstone floats in his pool on a tube and his wife Wilma brings his lunch. Barney startles her with his weird scuba-diving gear, which includes a bow and arrow. Barney accidentally shoots Fred's tube with his arrow, Fred sinks into the pool, and Barney rescues Fred's lunch.
Barney has invented something that looks to Fred like a giant egg beater, but it's a flying machine. Fred feigns illness so that he and Barney can get out of "opera night" with the girls and use the Flyer to go bowling instead.
A comedy of errors, starting with Barney's taking his last cold bottle of Cactus Cooler on a hot day, leads to Fred's getting hit on the head and knocked out. When he comes to, he is "Frederick," a suave and sophisticated gent who shortly gets on his wife's and his friends' nerves. Barney and the girls strive to find a way to get back the old Fred.
Barney has two tickets to the fights, but he and Fred can't use them because they've been trapped into babysitting a friend's child while their wives go out for the night. They can't even see the fight on TV, because there's a blackout. Then Fred comes up with an idea to get them into the arena after all.
Barney and Fred buy a drive-in but decide to keep the purchase a secret from the girls. The sexy young waitresses they inherit from the previous owner threaten not only to reveal the secret but to get them into trouble with their wives.
