There was a video of a magic trick I saw where the trick was almost certainly accomplished by false shuffles. I know how to do a few false shuffles, in theory, but, the magician (Ricky Jay, I think?) was just so good at the false shuffles that I was more impressed than if I didn't know how it was done.
