It used to be Star Trek Next Generation, I've seen each episode bazillions of times. Now, my favorite is NCIS, but I've only seen each episode a million times. I have some catching up to do.
Married with children.
Peggy is my idol!
I had to think long and hard because im over 40 and deciding on an all time fav is difficult. Ive had different top favs at different stages of my life. An 'all time' fav is difficult. Not sure i have one. My top favs for the past decade or so have been Brit shows i have on DVD. The Dr. Who seasons starting with Christopher Eccelstons incarnation, Torchwood, Broadchurch. I am finding American programming less and less palatable though i do enjoy NCIS and NCIS:New Orleans and i sort of like Scorpion. And Bones. And for a long while i got really into The Walking Dead. Most American programming is way too soap opera-y for my taste. Or too stupid.
I liked 24 with Kiefer Sutherland
The new 24 Legacy is pretty good
Blackadder
I really like and used to watch "Friends" ,"The good wife" and "Simpsons".
But all time favorite, hands down, "Game Of Thrones".
every time someone says TV show that's all I can think of.(even thought its books are better)
Happy Days.
"Just for laugh gags " and "Mr.Bean".
The Carol Burnett Show
More a movie person than tv shows its really hard to think i really use to like south park alot...
Law and Order, All - Everything.
Chicago all of them. Especially Med.
Whose line is it anyway!
All-time---that's too hard, but, current---that'd be Alaskan Bush People. Barely, though, as there are a few right up there with that one.
I would have to say Seinfeld . . .
They left while they were still hot in the ratings, and show always seem to find a new way to entertain.
