Phyllis Diller and Gypsy Rose Lee in The Pruitts of Southampton (1966)

Based on Patrick Dennis' novel House Party, this series ran for one season on ABC. The premise was that the Pruitts were broke, but because of their status and position, they were allowed by the IRS to keep their home and maintain the facade of wealth in order to protect the local economy. Behind closed doors, however, they had to maintain the house themselves, leading to many jokes having to do with Phyllis' less than stellar homemaking skills.

Carol Channing in The Carol Channing Show (1966)

So often when I run across pilots of sitcoms from the 60's that didn't make it I'm disappointed. It seems like such a raw deal that we didn't get to see what The Decorator would have been like as a full series. The year after Bette Davis filmed that, Carol Channing put a pilot together too. In it we follow small town Carol as she figures out how to break into show business and make her way in New York. It was produced by Desi Arnaz after his split with Lucy and is featured as a bonus on The Mothers In Law DVD. While it's not a brilliant concept, it beautifully showcases Carol in all her darling quirkiness, though I'm not sure how suited to situation comedy she was. It also features Richard Deacon and Jane Dulo as the couple who take a destitute (but remarkably well dressed) Carol in. The theme song is just wonderful and its no wonder - it was written by Jerry Herman.

This is only available in full on The Mothers In Law series DVD as a bonus feature. The opening sequence is above, uploaded to Photobucket by PhiladelphiaSon.

Obscurity factor: 10 (never aired, never screened, only available as a DVD extra)
