I think there’s some subtlety there you’re missing, and that is that there’s is a kind of pleasure and prankster humor in revealing to the more perceptive subset of the audience that you pulled an epic con, while still keeping the con alive for another less perceptive subset.

For an example of this kind of prankster game see Woz’s short videos about how he sources (actually real, but he intentionally does not say that) two dollar bills in pads from a local printer “who gets them from another very high quality printer.” He knows some people get what he’s doing and others don’t, and that’s part of the fun.

And some people transition during the exposition from being people who are being duped, to people who realize they were temporarily duped. That’s another part of the fun.
