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. (imdb)
