Oh, you evil, evil wench, Mallory! Now I have that song stuck in my head too!

It has a bit more of a history with me, though. An ex-ressie of our college used to play the piano at all our formal events. And always, at the end of the night, when the principal had left the hall and the wine had flowed far more freely than it ought, he would start up "Piano Man" and the entire hall would join him, swaying in time and singing with gay abandon, if not quite with technical accuracy.
