The slang phrase “going postal,” as in getting uncontrollably furious and violent, derives from tragic incidents involving United States Postal Service workers. Between 1986 and 1997, more than 40 people were murdered by spree killers in over 20 acts of workplace violence.  You know what hasn’t murdered 40 people?  E-mail.

A Catch-22 refers to an unsolvable logical dilemma.  The phrase comes from Joseph Heller’s 1961 novel “Catch-22.”  The number 22 has no significance.  Heller originally intended to call it “Catch-18,” but this was rejected by his publisher for being too similar to the title of another recently published war novel.  “Catch-11” was also proposed and rejected, due to its similarity to the film “Ocean’s Eleven” which was released in 1960.  “Catch-17” was then also rejected for similar reasons.  “Catch-14” was rejected because the publisher didn’t think 14 was a “funny number.”  If I were Joseph Heller, I would have just given up.  Clearly, there was no way he would win this battle with his publisher.
