On the way back from the Casino, Tony and Silvio have that long spiele on being Italian and he tells Silvio something like this:

"You've got a daughter at Lackawanna College and a wife who is a piece of ass. You own one of the most successful topless bars in North Jersey. Now, did you get that all because your Italian? No! You got it because you're you."
