There is a section in the middle where he tosses the cards into the audience that has been edited out for television. He teaches this and shows the performance in the download. Basically he has 3 people look at the prompts on the cards and he names their thoughts as well.
It's a 10 minute routine, where you can read at least 5 minds in a large theater with just a few cards. If you perform for large crowds often this is very good.
