From a reader:

Jonah:
Although there may be a wee bit of envy embedded in the comment from your reader, heshe is probably a bedside healthcare worker who knows the score. As you can imagine from my title below, I’m one of ’the multitude of college-educated, professionally -dressed big shots you see walking around in hospitals drawing six-figure salaries who HAVE NOTHING AT ALL TO DO WITH HELPING SICK PEOPLE GET BETTER!’ Indeed, when I walked into a hospital medical staff Executive Committee meeting one fine morning several years ago, the President of the medical staff, a family practitioner, glanced up and dryly exclaimed, ‘Here comes the overhead.’ a comment greeted with knowing, raucous laughter by all the physicians and executives seated around the table.

Me: Hey that explains why the suits at NR sometimes call me “O.H.”
