What's the name of that show I think was either on A&C or History or something like that, but the guy dressed really nice had a can & was a mind professor I believe he studied how peoples mind work and how they don't think while talking and in one episode he went to a fish market and paid for fish with paper and the fish guy didn't notice until the professor guy left the store but he said he's just going to walk around the block and come back to pay for it? Its been bugging me for two years now!
