The last time I sketched a real live human being was at a London comedy club in Soho a couple of years ago. A comedian came over to see the sketch I’d drawn of him. Reluctantly, I turned back the pages of my sketchbook mumbling get-out clauses (which stank of excuses) such as: ‘it’s only a rough’ or ‘I never went to art school’ or ‘my arm hurts’ etc…Anyway, this bloke grabbed my sketchbook, studied the artwork for a bit, then threw it on the floor: ‘That’s crap, it don’t look like me, you’re really f*cking sh*t at drawing’. He was about to punch me in the face, so I ducked.
