Joe Mooney was an Irish dog-racing trainer who "bumped into" Fred Gee, Terry Bradshaw and Alf Roberts when they went to the Regent Greyhound Stadium to enjoy a few bets. Joe spotted three potential mugs and fed them some blarney about their abilities in spotting a winning dog. He then told them a tale of woe about him having to return to Castleconnell in Ireland where his grandmother was in her dying days and he couldn't take his dog with him due to the quarantine laws. He offered them his dog, saying if they entered it in short races it was bound to win. The trio rejected his offer several times, but when Joe took them to the nearby Shamrock Club and got them plastered they ended up buying the hound with £30 of their winnings.
