A man, a ball, a hoop, a bench (and an alleged thread)… TELLER!

Penn amended Teller’s suggested explanation, offering “Now, here’s a trick that’s done with a piece of thread” in its place. Suddenly Penn was happy and excited. There was an idea. “That’s all,” Teller remembers Penn saying, “Just give them that much. That gives them so much and puts them on our side. Nobody else in the world would do that.

I saw Penn & Teller two weeks ago in Vegas. The show was amazing. The Red Ball act was awesome. And P&T are great personalities too.
