People come up to me on the street and make some little joke - like they'll say, 'Excuse me, sir, what time is it?' And I'll say, you know, '5:15,' and they'll say, 'Hey! Made you talk!' And that's merely a way of saying, 'I know your work and I like you.'
Every time you perform a magic trick, you're engaging in experimental psychology. If the audience asks, 'How the hell did he do that?' then the experiment was successful.
Sometimes, magic is just someone spending more time on something than anyone else might reasonably expect.
