This is a rip off of the story "Ed" told in the TV show "Northern Exposure", but it has always been one of my favorites from that show.

That Wikipedia page was created in 2020. Northern Exposure predates that.
Going with the OP's theme: if we repeat the GP's comment enough times, over a long enough period, we can change history and then history would really show it to have originated from the "story "Ed" told in the TV show 'Northern Exposure.'"
