I liked that scene. But, I think my favorite is early on, when Charlie and Johnny Boy are in the back of Tony's bar, and they do the "Is she the one on your left or my left" routine. Scorsese swears that scene was scripted, not ad libbed. You coulda fooled me.
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.
