At the Dog track
In this mystifying video, Derren Brown helps another man win at the dog track with losing tickets. Before each race, Derren has the gentleman bet on the dog he thinks will lose. Each time that dog comes in dead last. However, they get paid winnings by using a trick of the mind. He tells the guy to look the cashier in the eye and tell her he has a winning ticket. At first glance, they say it is a loser, when asked to take a second look; the cashier apologizes and pays the ticket.
