Then they both take a deep breath and start singing in perfect harmony. ‘Puggerlugs! Puggerlugs! Stop being bad!’ I’ve clearly gone fucking insane. ‘Puggerlugs! Puggerlugs! You’re making us sad!’ Stark staring bonkers. ‘Puggerlugs! Puggerlugs! To you we entreat!’ Completely off my bloody chump. ‘Puggerlugs! Puggerlugs! Be a good boy, and get a lovely treat!’ As if on cue, at the end of the song both Colin and Wilberforce hold out small doggie treats in their hands, dangling them temptingly in Puggerlugs’s direction.
