I'll add 2 more:
● (The New) Treasure Hunt... The only consistant, redundant aspect of that show was Ameile saying "Yes I Did". Otherwise, you couldn't really predict how they were going to award a prize or a Klunk to a contestant.
Also from the Barris files:
● The Newlywed Game (pre 90's eras in particular). From either/or questions, multiple choice questions (whose order was always changed once the couples were together again), defining words within questions ("What do you dip your cruller in??), whoopee questions,..etc.
