"Pimping" is a longstanding tradition on teaching rounds. An attending physician routinely grills residents and medical students, partially to make them squirm and partially to teach them. The questions can be about medicines, diseases, conditions, or totally random ("the song that's playing in the elevator, what year is it from, and who was the group's lead singer?" I'M NOT MAKING THAT UP!).
In the mid-90's I'd graduated from medical school and was in residency training to become a neurologist. In the time-honored tradition of wayward children, I'd gone to my parents' house to do laundry. I was folding it in the family room, while mom watched a medical show.
On TV a bunch of white-coated figures were on rounds. Suddenly a senior physician looked at a medical student and asked "He's an alcoholic. Why do we give him thiamine, and not just glucose?"
Without thinking, I answered the question aloud (you get conditioned to do that). A few seconds later, a guy on TV said the exact same thing I just had.
And my mother, in wide-eyed astonishment, looked at me and said "Hey! How did you know that?"
