Derren Brown

have you seen the one where Derren Brown goes to the dog track and wins £160 on losing tickets

he takes the losing betting slip to the window then bangs his hand at the side of the window and says `this is the dog your looking for, thats why we come to this WINdow` then he gets the winnings even though the woman behind the counter can read that its the losing ticket

he even points out her mistake, when she goes all scatty and fazed out he gives her a tenner and says `have a drink on us`.... Classic
