Who: Paulie Gatto
Note: Paulie says this after Clemenza says something to him in Italian (Clemenza asks Paulie if he farted in the car) while him, Rocco, and Clemenza joke around in the car. When they pull over for Clemenza to urinate on the side of the road, Rocco shoots him in the back of the head for betraying the Corleone Family.
