Remember the droll signs that used to get tacked up in storefront businesses and diners? They said things like, “Our credit manager is Helen Waite. If you want credit, go to Helen Waite.” Or “You don't have to be crazy to work here, but it helps.” Side-splitting. But there is such a thing as job-specific madness. Military commanders can sit around chatting over beer and pretzels while people are getting maimed and killed on their say-so. Comics feel compelled to expose their social anxiety defenses to drunk strangers. And pedal steel players? They deserve their own chapter in the DSM.
