I can honesty say, having watched several full episodes at other people’s houses plus umpteen clips, I haven’t cracked a single smile.
Bitches, please. That episode where DJ passes out at the gym is classic.
I disagree with a lot of the nominations. The worst shows aren’t the ones that are conspicuously bad (as Small Wonder); those at least afford a bit of campy fun. Instead it the shows that are utterly charmless, joyless, and forgettable, such as:
Millennium
Mr. Belvedere
Beauty and the Beast
Law and Order: SUV (does anyone really remember an episode of the show, and by “remember” I mean in a way that involves the actual content of the show and not just a vague sense of lurid unease and exploitation?)
South Park crypto-fascist garbage
Till Death - was that the one with the dad talking to a stuffed animal that came alive and talked back? Yes, that was it. Like the anti-Married With Children with a skanky homely skeleton for a daughter and a total lack of wit or humor.
Can I branch out into channels? The Golf Channel? (Not that golf is the worst thing on TV ever, but a whole channel??)
The sun with the baby face is something right out of Stephen King. Pre-verbal kiddies love the damn show, though. My granddaughter would stop whatever she was doing when it came on, just to stare at its horror, mesmerized.
Kids have no damn taste, which probably explains why I loved F Troop and My Mother the Car.
I’ve never seen it but it must be awful because it’s already been mentioned in this thread. I’ll take your word for it.
Ditto to Jackmannii’s nomination of the World’s Dumbest Criminals, and mostly because of Tonya Harding. The woman’s comments are lame (pun intended). I like to watch dumb criminals too, but we don’t need the D-list celebrity comments (Leif Garrett?) and the repetition of the clips.
Another lame guy is whoever does the commentary on the show with the bad drivers. Pompous, humorless voice, and inane commentary. “Here’s one driver who’ll be spending the night in jail!” And again with repetition of the clips.
My husband watches Blind Date. Anyone seen it? Send a guy and gal on a date. The gal is wired up to the guy’s former girlfriends who suggest questions to ask him. It’s not even embarrassing enough to be watchable.
I’m looking forward to More to Love, the new Bachelorette-type show with women of normal weight (which is slightly overweight). What do you want to bet they’ll be just as vapid as the skinny girls?
Oh, and I love Two and a Half Men. 
The Paula Poundstone Show.
I believe it was canceled in mid-episode. (Only half kidding).
Seconded. I had the displeasure of seeing some of these again recently. They had about five stock sequences of Spidey swinging on his web, and those same five sequences made up about thirty percent of each episode.
Cool theme song though. (However, the parody version over the credits at the end of The Simpsons Movie took it to a whole new level.)
I think some people are missing the point of the OP. I thought we were trying to identify the WORST television shows, not the ones Dopers don’t like. By that standard, Full House and Dukes of Hazzard should not make the list. Look, I hated Full House as much as the next guy, but it was popular with some demographic or another. It lasted what, 8 years? Sure it was cheesy, but kids watched it every week.
I do have to agree that Cop Rock sucked. I hope I am being wooshed by those that say they loved the show.

I thank Og that I didn’t watch Rosie Live last year, for its one episode. Did anyone here see it?
Were you not a member of our fighting forces, and known to me as a man of honor, I would have no choice but to slap you with a trout for saying that. [Cop Rock’s creation was proof of the existence of God, and its cancelling evidence that she or he was pissed with us.
Thanks a lot for reminding me of that abomination. OMFG, it had to be ***THE ***worst show of all time . . . and wildly popular for years.
I’m sure most of you mercifully never saw it. They might have a woman with terminal cancer, another whose baby died, another whose face was mangled in an accident, another whose kids were all in jail, another whose husband ran off with all their money. They all got to tell their stories and compete, with lots of sobbing, to see who could gain the most sympathy from the audience. The winner had to sit there, still in tears, while she received her crown, ermine cape and scepter; then was treated to a makeover and a private limo for the day, plus maybe an olive-green refrigerator or set of luggage.
“Babes.”
It was about three obese sisters (Marlene, Darlene and Charlene) who lived together in a NYC apartment. Dolly Parton was one of the show’s producers.
Kind of establishes an age threshold here, doesn’t it? 
But for us geezers, it’s still the benchmark of awfulness. And I still refer to it, like when Deal or No Deal (previously mentioned here) starts to wallow in their contestants lives and what they’d like to do with the money (and then they immediately pass on the $100k offer and wind up going home with $10)…I accuse the show of turning into Queen for a Day.
Indeed. Right up there with Jesse Spano’s caffeine freak out.
Still…I was surprised Full House only got two votes. The hatred for it is strong on this board!
Car 54 Where are You?
Gilligans Island
John and Kate + 8
Fox News
Hulk Hogan’s Daughter has a reality Show (Brooke knows Best)
The Kardasians
I still don’t think that quite approaches the number of shots/reuse ratio of the original Battlestar Galactica’s Cylon Raider footage.
Speaking of which, how can I possibly be the first person to nominate Galactica 1980?
Really? I don’t deny that Gilligan’s Island was stupid beyond measure (a real group of castaways probably would have killed and eaten Gilligan–or at least set him adrift on a raft–halfway through the first season), but a lot of people (including me) have a nostalgic soft spot for it. It did have a certain '70s charm.
I challenge anyone to search youTube for The Half-Hour News Hour, though I will not be held responsible for the subsequent injuries resulting from your brain trying desperately to break free of your skull and flee in terror.
