Looks like I've got two answers to give.
First, on my post above "Va fatti a cazza tuoi" is from Clemenza to Paulie at Connie's wedding reception. Paulie: "Ahh, you look terrif on the dance floor!" Clemenza: "What are you a dance judge or sumptin'? Va fatti a cazza tuoi! Go take a walk around the house - do your job!"
As for this quote, it is Michael to Joey Zaza as he received the Marucci Award as Italian American of the Year in GF III.
My new quote question (No italian, I promise)
"Hello? I have a collect call from a Mr. Michael Corleone. Will you accept the charges?"
