I made a post earlier today about Penn and Teller and a few of their online clips. I was going to search for some clips of Teller speaking, but I ended up getting sidetracked and working on something else. Anyways, on the Ellusionist blog they posted a video of Teller explaining the psychology of magic.
I remember reading an article about this presentation about a year ago on reddit.com I thought, but I can’t seem to find it now. Anyways, it’s much better to see the video of it anyways.
I also found some other videos of Teller speaking as well.
Here’s a clip of Teller speaking in a deleted scene from “Fantasticks”
