To add to the understanding of Penn and Teller, they love their fans and beyond. I've been to two of their shows and their efforts are to entertain and teach you about scams and confidence games so that you question what you see and are being told. They go to great lengths to tell you how they are scamming you and then show you the trick and still trick you so you aren't so confident. You're not as smart as you think you are. At the end of the show they meet with the audience at the main entrance to take pictures with them and show their appreciation. They should be a high school credit.
