Jimmy enjoyed a stunt in which he would walk over a sidewalk grating, make a great “swooshing” sound, and lift his overcoat over his head. Marty, who was walking about ten feet behind him, would run up. “Good grief! What was that?” Marty would scream. “I don’t know! I don’t know!” Jimmy would cry. “It came from down there. I think something’s about to explode.” When a sufficiently huge crowd had gathered and the braver ones were trying to work up their nerve to approach the grating, Jimmy and Marty would steal away, cross the street and watch the excitement from there. “Some bunch, aren’t they?” Jimmy would say, smiling broadly.
