I liked the banter in the car between Clemenza, Paulie and Rocco, after the search for matresses, just before Clemenza tells Paulie to pull over so he can take a leak. They're there for one purpose--kill Paulie--and, like boys will be boys, someone farts in the car and they all joke about it.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
