I never got into too many sitcoms, although I loved the Golden Girls and All in the Family for the ensemble performances--practically a dead art these days.
I remember that show. He WAS playing James Thurber. It was too cerebral.
Incidentally, speaking of sitcoms, one of my FAV sitcoms and I think it is the funniest and most intelligently written sitcom ever written (with gay actors and gay characters) is FRASIER.
I never liked CHEERS, but I think FRASIER is the BEST. LOL
