WAIT TILL YOUR FATHER GETS HOME, the only successful, animated sitcom in the 27 year gap between the FLINTSTONES and SIMPSONS, progresses to its 18th regular episode...
When proximity to the ocean turns-out not to be the best beat-the-heat strategy anymore, Harry goes-in with neighbor Ralph on installing a swimming pool. Conflict follows.
The neighbors friction over a swimming pool was reminiscent of HB's third episode of the Flintstones from thirteen years earlier... Which was, in turn, expanded from the original pilot for the Modern Stone Age series.
From January 1973.
