QUIZ GAME

Paulie Gatto is a mobster who works for the Corleone family, and is a trusted soldier in the crew of Peter Clemenza. 
The Don's son Sonny discovers that Paulie helped Virgil Sollozzo and the Tattaglia Family set up Don Corleone to be assassinated. 
Through Family contacts with the phone company, Sonny learns of numerous calls between Paulie and Sollozzo/Tattaglia contacts.
Sonny orders Clemenza to kill Paulie. 
Having trained Paulie himself, Clemenza considers his protegé's treachery a personal insult.
Clemenza decides to use one of his top associates, Rocco Lampone, on the hit to give Lampone a chance to "make his bones".
