G used to get pressure build up in his shoulders and neck, the muscles used to get really hard. He'd tilt his head to his shoulder and it would crack really loud! People would look in horror sometimes as it sounded painful. But he'd always say the same thing after "ahhh that's better and smile." He also used to bend his knees to make them crack whilst standing, he'd drop his knees slightly, and they'd let source crunch, something he got from his Mum! X
