Overweight Australian DJ. Karl claims it's ironic that he DJs on 'Heart' FM as he's wrecking his own. Always wears shorts not trousers, possibly for medical or fiscal reasons. Mentioned several times on the Xfm show hosted by Ricky Gervais, Stephen Merchant and Karl Pilkington for his appearance on Celebrity Fat Club. Along with Rik Waller, Gervais and Co. use Coleman's name as a short-hand term for "fat man".
