If he got no response from the audience after a joke, he would often add "...when this ovation has died down, of course." The delayed punchline to handing the person the sheet music would come when he would reach the end of a number and begin playing the penultimate notes over and over, with a puzzled look. He would then go back to the person in the audience, retrieve the sheet music, tear off a piece of it, stick it on the piano, and play the last couple of notes from it.
