To me, there's very few game show sound effects that have wedged themselves as deep into my mind as Greed's "un-suspenseful miss" sound: getting a question wrong much earlier than anticipated, either by missing one of the early gimme questions or getting multiple wrong answers on the "4 of x" format questions
It's difficult for me to even describe it, it's kind of like a record-scratch? But it's sure been stuck in my mind for 23 years
I think part of the reason it stuck in my mind so well was that it's such a rare sound to hear in the context of that game, most teams did not screw up anywhere near badly enough to get to that point
So hearing it at all meant things had flown entirely off the rails
