They’d tell you what the movie was, but they’d have to search for it and don’t want to waste an hour.
Jokes aside, I believe them, I spent close to an hour recently finding a YouTube I knew existed but I could only remember vague details. Ended up having crawl back months though my YouTube history in the end.
It used to be that you could just describe a movie to Google like "movie where " and it would be really good at finding that movie even if it was some obscure one. Now if you’re trying to find that one movie you saw years ago where you just remember one scene, be prepared to spend that hour.
