Some great ones.
50s/60s.......The Honeymooners, Bilko, I Love Lucy, Bewitched
70s.....M.A.S.H, Taxi, WKRP Cincinnati, Happy Days
80s....Cheers, Seinfeldt, Larry Sanders Show
90s.....Friends, Fraser, Just Shoot Me,
This century......Californication, Curb Your Enthusiasm, 30 Rock,
Seinfeld is a 90s show.
Friends making anyone's list makes me question their character, but you have Curb, Frasier, Seinfeld, and 30 rock all on your list so I trust you're a good guy. Just shoot me is also really overlooked.
Those would be mine, plus south park.
I really judge anyone harshly also who puts family guy as good comedy. Seth McFarlane is a douche, and that show struggles with any good jokes connected to the plot. If their is one.
