I had a client contact me about a problem he was having with some
other design (not one of mine).  Begrudgingly, I offered to help
(I don't like having to troubleshoot other designs as you never
know the quality of the design/designer).

It quickly became apparent that one device was bad in every sample.
On closer inspection, there was no die *in* the package!
