Where does this phrase originate from? Google says The Incredibles but that’s impossible since we said this when I was a kid. I have a vague memory of someone either in a suit or lab coat saying it , maybe in a parody of an In Search Of type show. Does anyone know for sure?

As an old person, I remember it long before Bill and Ted.
