The Flagstones (The Lost Pilot)

This pilot was merged with one of the early Flinstones episodes, "The Swimming Pool". In this one, Fred Flagstone was resting in his pool on a tube and his wife Wilma brings his lunch. Afterwards, she was scared by Barney's weird scuba diving look. Wanting to show Flagstone his new suit with his bow and arrow, he accidentally shoots it and the arrow goes into the tube. Flagstone sinks into the water quickly...and Barney grabs the lunch !
