Magic's about understanding - and then manipulating - how viewers digest the sensory information.

People do not come to a Penn & Teller show to see a magic show. They just don't. They come to see weird stuff that they can see no place else, that will make them laugh and make the little hairs stand up on the backs of their necks.

Indian street magic tends to be very gory, blood and guts. One trick is for a magician to take a knife and appear to cut his kid's head almost off. The magician then says to the crowd, 'Well I can continue to cut off my son's head or you can all give me some money.' Then he wanders around and takes 10 rupees from everyone and restores his son.

Comedically, unpleasantness is great fun.

The history of exploration across nations and across time is not one where nations said, 'Let's explore because it's fun.' It was, 'Let's explore so that we can claim lands for our country, so that we can open up new trade routes; let's explore so we can become more powerful.'

I'm on this extraordinary adventure, and if I have no one to talk to at the end of the night, I feel lonely.

Screenplays I didn't really care about, journalism, travel books, getting my writer friends to write about their dreams or something. I just determined to write the books I had to write.
