Does anyone know if Wayne's version uses the scenario, or is there any rhyme or reason to the deals there?
In the Big Deal Wayne always reveals one the of the lessor deals first. One of the players who most likely knew the puzzle asked Wayne "Can I switch now?" Without hesitation he answered, "No"
I don't know if he still does this (I haven't watched in a while) but in the early going, after revealing one of the lesser deals, he'd say something like "Now you have a fifty-fifty chance". It's a small thing, but that fallacy lies at the heart of why some people don't understand the problem.
