I was walking through one of the units where I work yesterday when I overheard two nurses looking at a patient's schedule for the day:
Nurse #1: "What's this thing on the schedule? PM...R? What's that?"
Nurse #2: "I have no idea."
Nurse #1: "Oh, here's Dr. McFizz, maybe she knows. Dr. McFizz, do you know what PMR means?"
Me: "You're kidding me."
They weren't kidding me.
