Fernwood 2-Nite with Martin Mull was hilarious. I wish I could find that on DVD. Later became America 2-Nite.
Police Squad was brilliant but the humour in it was too advanced because it made people think and people didn't want to use their brain for a half hour sit-com. Those were the words of critics on the reason for the failure of the show. I have every episode and watch them at least a few times a year!
Venus Flytrap did not say it. Johnny Fever said, "WKRP in Cincinnati, where we have more music and Les Nessman!"
For sheer comic brilliance the funniest show in history has to be the first season of Mork & Mindy but unfortunately the magic did not last.
Honeymooners lasted on 39 episodes but every one of them are classics, especially the one with Ralph as the game show contestant.
My favourite 3 runner-ups are.... 1. Three's Company
2. Beverly Hillbillies
3. Cheers and Frasier
and the winner of the greatest sit-com in history is.... The Simpsons, no question and no debate!!!!
