I can envision this being like Shark Tank, but with the added benefit of educating uninformed minds as to why these people are idiots.

The gimmick only really works from season to season if you occasionally allow one of these freaks to win.

Also sets up this ridiculous standard of “debate”, wherein arguing over a thing is considered more important than actually understanding a thing. Episode after episode of people making increasingly fanciful claims and fraudulent proofs will simply reinforce the idea that the Earth is, in fact, flat. If you have a parade of people asserting with supreme confidence that this theory is true, you create the impression that there is some serious doubt about the shape of the planet.
