as delivered by the great Walter Matthau in the film "A Face in the Crowd"
"Suppose I tell you exactly what's gonna happen to you. You're gonna be back in television. Only it won't be quite the same as it was before.
There'll be a reasonable cooling-off period and then somebody will say: "Why don't we try him again in a inexpensive format. People's memories aren't too long."
And you know, in a way, he'll be right. Some of the people will forget, and some of them won't.
Oh, you'll have a show. Maybe not the best hour or, you know, top 10. Maybe not even in the top 35. But you'll have a show.
It just won't be quite the same as it was before. Then a couple of new fellas will come along. And pretty soon, a lot of your fans will be flocking around them. And then one day, somebody'll ask: "Whatever happened to ...whatshisname? You know, the one who was so big. The number-one fella a couple of years ago. He was famous. How can we forget a name like that? Oh by the way, have you seen, a, Barry Mills? I think he's the greatest thing since Will Rogers."
