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.

Funny Moments: As noted in a book of bloopers by Kermit Schaefer...
Questioner: First you open my drawer, then you make a sale. What am I? King of the Hill: A hooker! (the correct answer was "a cash register")
Most egregiously, the questions changed from riddles to general-knowledge questions of the yes-no, true-false, and multiple-choice varieties.
The Target Number and Multiplier were dropped, with the Super Jackpot being established for a random amount from $2,000 to $10,000. This was far less than the $20,000+ Super Jackpots offered previously, and could actually end up being worth less than the Jackpot.
If the Jackpot Question was found, the Expert could either try to answer it right then, or go for the Super Jackpot by answering all of the other remaining questions in the game, including the Jackpot Question. If the Expert missed any of the remaining questions, the Jackpot was reset to $0 and a new Super Jackpot value was set — but if the Jackpot Question was the last one picked, the Super Jackpot was discarded.
While the June 9, 1984 pilot marked the return to riddles, they were worth $150 with no Super Jackpot; instead, leaving the Jackpot Riddle until last added $5,000 to it. The pilot also had a bonus round ("Riddlegrams", recycled from Stewart's Shoot For The Stars and later into Double Talk) which didn't fit with the show's premise, along with being played only by the person holding the Jackpot Riddle and the then-current King/Queen of the Hill (an idea somewhat recycled from Stewart's unsold 1982 pilot Twisters).
