The program director of our i.med program said that he sometimes asks this question - he said that if someone answers "clean up", then grab them as they might be a potential primary care physician! He did say that the "bring something" answer didn't exclude candidates from being ranked high. He didn't say how many people had opted to clean up - I got the impression that it wasn't many.
And before anyone jumps all over me - it was all part of a light hearted lunch meeting. Anyway, as a primary care resident in a sub-sub-specialist facility I certainly feel as though I'm left to clear up far too often.
