New story to me, at a guess he understood that the design had created a shorted turn so a cut in the casing would solve it. The principle of the story is however exactly the same as one I've heard before about Picasso:- Picasso is quietly having lunch at a cafe when this loud woman says "Hey, aren't you Pablo Picasso?". He replies, quietly, "Yes, Madam, I am". Her: "Wow! Hey, will you do a little sketch on this napkin for me?". Picasso demurs, but she's really insistent. She says "It's only take you a moment, and I'll pay whatever you think it's worth". So Picasso whips off a quick pencil sketch, 10 seconds, hands it to her. "Here you are, Madam. That'll be $10,000 please". Her: "$10,000?! It only took you a moment!" Picasso: "Au contraire Madam, that took me my whole life."
