Its a pretty serious weird coincidence that basically everyone remembers it
"Basically everyone" "remembers" things that are incorrect quite frequently.
Memory is especially egregious. Human memory isn't like computer memory where things will stay exactly as they were years or decades into the future unless there's some freak accident.
Human memory is mostly bits and pieces that get recreated when those memories are recalled. The brain fills in the gaps using rules of thumb and patterns that "make sense".
If you're interested, you can look into research on the fallibility of eye witness testimony -- Elizabeth Loftus is/was a key researcher in that area.
