How not to respond to a rejection letter

A colleague elsewhere showed me the response to a rejection letter from a candidate who basically wrote back to say, sarcastically, "I can understand why you hired John Smith, even though he has far fewer publications than me in the same area." In fact, people are not hired by counting up their total publications; responsible hiring committees actually read the publications and writing samples of their finalists.  Someone who sends a response like this assumes, falsely, that quantity of publication is what should matter and implies, probably unfairly and obviously self-servingly, that the hiring committee was unable to make a qualitative evaluation of the work.  Since word of these kinds of replies do get around, the candidate is not doing himself any favors.
