Penn & Teller put on a great show. It's witty and cynical and everything you expect, plus magic! They are also great with the audience, involving many in their illusions and tricks and letting them keep props as souvenirs. Case in point, one person in our group became an involuntary participant when one of the props used ended up under his seat. It was just mind-boggling how it ended up there. Trap-door? Sneaky stagehand?
Some tricks may be familiar if you've watched Fool Us or Bullsh*t...but it's still pretty cool to see live. Additionally, it was much appreciated that they spent a large portion of the aftershow signing autographs and taking photos with guests.
If you ever wanted to hear Teller talk, that's your opening. It was weird, haha!
