I made a mind blowing discovery at my new job today. I know that our company assigns serial numbers in numeric order starting at 1 for all serialized parts. Some parts, bought from vendors, get a two letter prefix. I found a part TK1348; therefore somewhere in this company is a part labeled #TK421. It is now my hope to see this part in our lab and say unto it, "TK421, why aren't you at your post?"
