"That could ease you and cool you and cease the pain/Of your useless and pointless knowledge..."
Oh, it's crossed my mind occasionally, over the last 25 years, to resort to a Bob Dylan lyric — notably, that one — when a law student has asked me for the wrong kind of answer. I managed to resist. Now, imagine a law professor — a Harvard Law professor — making an exam out of 2 nothing questions and tossing in a Dylan quote as a taunt — "'There must be some way out of here,' said the joker to the thief/'There’s too much confusion, I can’t get no relief,'"
Via Instapundit, Elie Mystal gives Professor Charles Nesson a pass.
That exam — which you can read at the last link — reminds me of an anxiety dream I once had. I suddenly realized I had to give an exam. The students were all in the room ready to go, and I had nothing to hand out. All I could think of to do was to walk up and begin to write on the blackboard, making up the exam questions as I formed the letters of the words. Beginning with a Dylan quote would be a useful way to stall while scrambling for something that could plausibly be considered an exam question.... before going insane.
