USA: We need 100,000 integrated circuits, with a defect rate of 1 in 10,000. Can you do that?
JPN: Well... that's very difficult. But I think... yes, yes I think we can do it.
6 months later, he returns with a very large box and a very small one
JPN: This was much more difficult than we thought, but we managed to modify our processes to obtain the exact defect rate you requested. Here are the defect-free chips.
USA: Well, I'm very impressed! To be honest, I didn't think you could do it. But tell me, what's in the small box?
JPN: Those are the 10 defects.
