Piccolino

That lil rat snitched on Richie to Gino, that's the only reason Gino had any clue where to find the crew at the end. Heck, Piccolino would have probably made a better cop than Gino.

By the way, that was the sorriest excuse for the Italian mafia. Richie basically wacked half of Vittorio's crew without them getting revenge. And the way Gino totally insubordinated the don at dinner would have gotten him in the trunk and at the bottom of the Hudson river if that mob family was worth anything. If Gino had talked smack to Vito Corleone, he wouldn't have made it out of that restaurant alive.

That said, this movie should have won for best picture, director, and supporting actress (Terry, the waitress with the n*pples you could dial a phone with). LOL
