OHMYGOSSIP — Samantha Giles digs her fingernails into her hands to stop herself from spoiling ‘Emmerdale’ scenes by laughing. The 47-year-old actress’ co-star Jonny McPherson – who plays Doctor Jonathan Boam – has also taken on the tactic to stop himself from cracking up during filming, and he has been left with “bruised palms” as a result. Speaking about shooting scenes with Samantha (Bernice Blackstock), he said: “It would be easier to count the ones where we have kept a straight face. “Once Sam has gone, that’s it. She has a tactic of digging her fingernails into the palm of her hand to stop her from laughing, which I’ve adopted. “I have bruised palms by the end of a scene. She’s a terrible influence.” Jonny insists he and Sam are “never” awkward when they are filming intimate scenes because they are “good friends”. He added to Inside Soap magazine: “On the first day of a new job you might have to kiss someone, and it can be very peculiar situation to stick yourself in. “But Sam and I are good friends, and we’re really comfortable with each other.” And Sam and Jonny aren’t the only soap stars who inflict pain on themselves to stop cracking up in a scene. ‘Coronation Street’ actor Simon Gregson – who plays Steve McDonald on the ITV soap – recently revealed his co-star Ben Price (Nick Tilsley) has to stab himself with a toothpick to stop himself laughing. He said: “I love working with Chris Gascoyne and Ben Price, before now Ben has had to have a toothpick to stick in his hand to stop him laughing in a scene.”
