These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Moment of Awesome: Champion Hal Shear was in dire straits in his eighth game, against Adrienne. Down $500-$200 and with no Fast Forward category available, his only hope was to spin three Jokers, which would give him a chance at an instant win. Luckily, he was wearing a rather loud "lucky suit". He gave it a quick rub, pulled the handle, and got his three Jokers. After Barry nearly fainted from shock, he explained how astronomical the odds would be of someone both needing and getting three Jokers. Hal proceeded to get a very simple question right and won his game. A bit of a Downer Ending for Adrienne, though...
This clip shows a rare case in "How Low Will You Go?". While the contestant could have up to seven more clues to answer a question, she asks for NO more clues and still gets it right!
1983: Barry sadly sends off Joe Dunn as an undefeated champ by showing his accomplishments, including $66,200 in cash and prizes. This was also when the network limit on game show winnings was raised to $50,000 from the previous $35,000 (while the show itself was syndicated, it ran on network stations and hence subject to network rules), with a charity of the player's choice receiving what went over that. This was 21 years before Ken Jennings on Jeopardy!, and was a big deal as Dunn had been a regular champ and hadn't yet played in a Tournament.
Byron Wilson, who came back from a $400-$0 deficit by answering ten $50 Fast Forward questions in a row.
Nightmare Fuel: If you were a young child in that era, the devious rendering of the Devil's face (supposedly a caricature of Barry) kept you up at night quite a few times...although for the 1990s version, it was very likely replaced by the Joker.
Replacement Scrappy: Much hatred for the monotonous Pat Finn. Also, many fans disliked Bill Cullen's run on the show; while he's usually praised as one of the best game show hosts of all time (if not the best), Bill's laid-back hosting style wasn't a good fit for Joker, and old age had slowed him down considerably by this point.
They Changed It, Now It Sucks: Much hatred for the 1990s maingame and bonus round (first word, first definition...). The categories returned on January 7, 1991, but the measure came far too late to save the show...and the money-based format came back for the last three shows anyway to avoid straddling.
Further, the question values were $25/$50/$100 (half of what they'd been just five years earlier). The Jokers couldn't be used to go "off the board", as they hadn't let the contestants know what categories each game had on the reels (they had to be used for the full amount for whatever category was chosen). Spinning three Jokers gave that player $250 and the right to answer $100 questions in one of three categories hidden behind each Joker. Not like before.
What an Idiot: One of the special categories added was "Fast Forward _____" (debuted May 16, 1975), which allowed contestants to keep answering questions as long as they kept getting the right answer, each right answer adding the same amount to their score. In one game, the champion had $250 and needed to tie or beat the challenger who had reached $500. The champion spun a Joker and two regular categories then, without thinking, asked for "(Regular Category) for $200". An amazed Barry told him that he just lost the game, when the contestant should've gone off the board with the Joker and taken the Fast Forward to build up $50 or $100 questions and possibly win the game.
