Grand Theft Auto:Vice City, has a mission called "Keep your friends close..." And there was this spoof Mafia movie, (I remember it had a scene in it where a tall guy was dressed as a priest, and a midget came out with a machine gun, and the priest said " Say hello to my little friend" when they at a funeral. I know that it is a Scarface reference, but I'm sure it had some refeences to the Godfather.)
