The Big Plot Twist

[youtube https://www.youtube.com/watch?v=JSOwlXJj67Y&w=942&h=530]...is that we are all characters in a bad work of fiction. It was a staple of the Twilight Zone and at least one science fiction story I can think of. I read it when I was a kid. The protagonist was this pathetic schmo whose whole life has been one ridiculous pratfall after another. At the end, he finds out that he is the comic relief in a Truman-show like TV production. Somehow he finds the producer, pitches a plot twist in which he becomes the hero, and turns his fortunes around. It was a silly premise but memorable enough that I never forgot it.It doesn't seem possible, but this is apparently true. It even features the "I alone can save you, believe me" riff. Could it be that the writers of the story that we are all supernumeraries in are so lazy that they are plagiarizing a ‘50s TV show? Click the video; you'll be relieved to see that it ends with Trump's arrest.
