I've been predicting for a while now that the tattoo fashion would lead to a profitable trade in tattoo removal.

My parents had a collection of cartoons from Punch that gave me many hours of pleasure in my youth. I think it was there that I saw one which has come to mind often since the fad began: a tattoo artist drawing something huge on a man's back and remarking "Of course it's the fellows who can take them off who make the real money."
