This week the lads welcomed Rob Hartnett to Fitzpatrick's Castle in a bid to learn more about the commercial side of sport. Rob Hartnett is the CEO of Sport for Business and one of the men behind the biggest sport and technology conference in Ireland this year, The One Zero Con, in Dublin's RDS. The One Zero Con takes place October 21st and key note speakers include Lance Armstrong, Sir Clive Woodward and Shane Lowry. Rob joins the lads around the 47 minute mark of the podcast but before Rob popped into the studio at Fitzpatrick's Danny and Mero went about solving some of life's great mysteries. Mysteries like where do sayings come from and is it true Adolf Hitler had a brother who roamed the streets of Dublin?
