I absolutely love this: "The Miami Herald published an article in 1981 about an 89-year-old man named Sammy James. James had worked for decades as a crate nailer and said his fast moves earned him the nickname, "The Nailer.""

His job title was a crate nailer, but he got the nickname from his fast moves. That's like being so good at operating the cash register you earn the nickname "The Cashier"
