Rubbing it in.

This morning all of the students were greeted with the announcement that "new, metal folding chairs" were now available, in case the older, plastic chairs currently in use were not satisfactory. We were instructed not to rush over and get one, so as to not cause a mob of students eager to trade in one form of Chinese torture for an even more uncomfortable, spine-morphing sort of chair. Perhaps this was in response to the student who fell on his ass when one of the older plastic chairs exploded in the middle of lecture.
