I thought it should be noted for posterity that "The Clampetts Meet Mrs Drysdale" is the 4th episode from the first season and it first aired on CBS on October 17, 1962. Source: Wikipedia; List of The Beverly Hillbillies episodes.

Watching these early episodes is a treat for me as most of the reruns I watched over the years were from later seasons. Its neat to see how the show began and progressed as the cast and overall production became a little more polished as the episodes and seasons moved forward.
The Beverly Hillbillies is still one of my all time favorite programs and I offer many thanks to the contributor for posting and to the Internet Archive for hosting this wonderful slice of television history.
