I found a few clips from various Penn & Teller magic shows on YouTube a few days ago. Then I found some full episodes from a show they did in England called “The Unpleasant World of Penn & Teller”. They are good for that gory magic that Penn & Teller are known for and if you are going to watch “Penn & Teller: Fool Us” a new show thats in production. I suggest you check them out.
Look in the related videos for more episodes.
