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.
Big Lipped Alligator Moment: When the animated "Hickory, Dickory, Dock" opening was introduced on December 20, 1952, the animation was followed by shots of people laughing against a dark background. The laughing segment, which was removed on February 14, 1953, had no bearing on the show and was hardly mentioned. Also counts as Nightmare Fuel.
Memetic Mutation: The British version gave rise to the risqué slang "Beat the clock", referring to an attempt to complete A Date with Rosie Palms before the five free minutes at the start of the porn film end.
The switch to all-celebrities on the Hall version, a mere two months into its four-and-a-half month run.
The PAX version used a digital Clock for most of its stunts (the Whirlwind had a more physical Clock), threw out a lot of the gunge, and...well, if even a stunt show feels like the stakes are too low, you have a problem.
