Wake up little Susie, Wake up

Law professor Michael Froomkin has a sleeper in his early morning class, which leads to this story —

The whole incident reminds me, albeit somewhat uncomfortably, of a story that was popular when I was a law student at Yale. Myres McDougal, the great international lawyer, was emeritus by the time I got there, but his v e r y slow southern drawl was as distinctive as ever. The story was that when, as a young man, he had taught at Columbia, they had given him a lecture room with a ground floor and a balcony. Supposedly, one of the Columbia students fell asleep in the front row of the balcony. McDougal looked as his seating chart, called on the student next to the sleeper and asked him to please waken his colleague.

The student supposedly responded, “You put him to sleep, you wake him up.”
