Watched a 1975 Johnny Carson episode on Antenna TV tonight (Saturday, 2/6) and saw a "new" Carson pieing that may not have been seen since it originally aired!
Johnny intros it as an audience "secret fantasy". It features Johnny as an economist in gray slacks and gold sweater, bald and with glasses, sitting in a den setting. As he continues speaking the camera gets closer and closer until finally... SPLAT! Very similar pie to what has been seen on the other famous Carson pie clips.
This 1975 show featured Joan Rivers, Truman Capote, and Bob Speca (domino wizard).
Keep your eyes peeled to these Antenna TV broadcasts (especially the 70s ones on the weekend)! You never know what's been forgotten or "lost" since the original airings, especially since Johnny's shows were stored in a special underground mine these last 40 years (true!) and are only now being shown.
