The finale of the second series, it's the first scene of the episode so shouldn't be too difficult to find and put up for someone more computer savvy than me. It starts with Rosie screaming from the bedroom and then running out while being chased by her brothers, who take her down to the floor and tickle her stomach as she laughs (brilliant laughter by the way, believable that she's actually being tickled). Katie Findlay is so hot, so this is a brilliant and unexpected tickle scene.
