Oh, Man....
....There are so many.
First and foremost, I miss CBS's powerhouse Saturday night lineup of the early '70s, which included my personal all-time favourite, The Mary Tyler Moore Show.
That same night, you'd get:
All In the Family
The Bob Newhart Show
The Mary Tyler Moore Show
The Carol Burnett Show
And one other half-hour sitcom, which changed over the years. One I remember with especial fondness was Bridget Loves Bernie, with David Birney and Meredith Baxter, before she turned into The Great Stone Face of cheesy made-for-TV dramas.
Others include:
The Mothers-In-Law
Make Room for Daddy
December Bride
Pete 'n Gladys (a spin-off of December Bride)
The Dick Van Dyke Show
The Smothers Brothers Comedy Hour
The Sonny & Cher Comedy Hour
The Jack Benny Show (his 1958 violin competition with Gisele MacKenzie is one of the funniest things I've ever seen)
Laugh-In
Roseanne
Grace Under Fire
I've become very fond of Britcoms in recent years, because American television can't seem to come with good sitcoms any more, and because British shows manage to be both more civil and funnier than the ones over here:
Waiting for God
Are You Being Served?
To the Manor Born
As Time Goes By
Last of the Summer Wine
Yes, Minister
Yes, Prime Minister
Fawlty Towers
The Vicar of Dibley
My liking for British TV is not absolute; I have never liked Keeping Up Appearances, and if I never see another episode of My Hero, Red Dwarf, or A Fine Romance it will be perfectly fine with me.
