What’s the difference between a bond and a bond trader?

(Answer: “The bond eventually matures.”) This old joke came to mind when I read in the FT that Deutsche Bank doesn't want traders to use bad or indiscrete language. Colin Fen, co-head of investment banking wrote to employees that "some of you are falling way short of our established standards [sic]." . . . "Let's be clear; our reputation is everything. Being boastful, indiscrete and vulgar is not o.k. It will have serious consequences for your career. And I have lost patience on this issue."
