My grandmother identified all the people in the car off of her memory, so I don't believe in that one. 5 or 6 people idr but she said the correct number.
The 3PO thing was weird, I only saw star wars once so I'm not a good frame of reference, but I didn't remember the silver leg.
My neighbor who thinks flat earth is insane swears it was called jiffy peanut butter, and believes reality has changed. Also with fruit loops too.
For me the Forrest Gump one changed, Mr. Rodgers Neighborhood theme I watched all the time and that seems like I wouldn't have got it wrong, and I could have swore hannibal lecture said "hello clarice", even jim carey repeats the line in The Cable Guy.
Of course it was berenstein, berenstain looks weird and we would have at least heard someone mispronounce it ONCE.
IDK if you saw field of dreams, but it was like a plot point that he said "build it they will come", until the very last time when it changes to "he", I saw the movie on a bus going to a yankee game when I was like 10, and I had nothing to do but focus on the movie and I "know" it changed. There is even a movie where they play that movie in the background, and the actor in the movie hears the line and repeats it the old way while it plays the "new" way in the background, very weird.
Have you seen "the elephant man", hadn't seen it before the supposed change, but it changes dramatically.
I'm willing to believe we all misheard and misread, but at the same time I'm not. I have no explanation for how or why this can happen. It almost seems more logical that reality shifted than it is that we all misperceived everything and never corrected one another. Maybe things sounded differently on tube tvs, but that doesn't explain barenstain.
I honestly try not to think about it
