Seinfeld was a “show about nothing,” and it would be a desolate sight to see some 60-somethings do the same things they were doing three decades ago.

Back in the 90's Carroll O'Connor wanted to do some type of Archie Bunker revisit (for lack of a better term), his idea was to have Archie working as a limo driver, Lear put the kibosh on the idea immediately and that was that.
