Somebody on the Dr. Oz staff must be a real game show fan.  It's common late in the show for them to do some sort of simple game involving answers to health questions.  Every once in a while, they'll do something that is specifically based on a real game show, like a Pyramid game or something.  Monday I happened to catch, of all things, a Million Dollar Money Drop game.  They did it for real stakes (though only $500) and what I found interesting was how engaging it was even with a simple set and a smaller amount of cash on the line.  I'd love to see this tried again in some lower-stakes, faster-paced version.
