Cameraman: "Right, don't put too much weight on it, right?"

Poor Lad: "Where the fuck am I meant to put my weight? I can't put my weight on the roof, it's dead thin, I can't hold on to the gutter what am I meant to do with it? Oh here Andrew, hold it for five minutes, you fucking wank stain! Don't put- Don't shift your weight- What the fuck are you talking about? I can't put my weight on the -fucking- the roof, I can't put my weight on the gutter, where is it meant to go?"
