I was going to mention the "Commendatore" scene. Another priceless Paulie scene (but not just with Paulie) was when he and Ralphie had their sit-down. Ralphie was late, and Paulie called him out on it. Ralphie replied, "Well, next month I might be on time, but next month you'll still be stupid." Paulie's look at him and his leap were both tops.
