Much of that impression was imparted by the use of a learned accent called the Mid-Atlantic accent. It was a quasi-English accent that was taught in schools as a way to sound more upper-crust. John Daly is a pro at it. So were Dorothy and Arlene. What makes me laugh are the guest panelists who tried to adopt it to sound more erudite. My favorite is when Johnny Carson appeared. He totally changed from a wacky comedian to kind of a stuffed shirt.
Delightful, and a reflection on when television (at least Stateside) was entertaining without the need for purposeful misinformation. Now...soapbox safely stowed away...find and view the hands-down best contestant before the blindfolded celebrity panel, one Salvador Dali ("Yes?").
