Gatto is Peter Clemenza’s handpicked protégé and Don Vito Corleone’s bodyguard. Paulie works for Clemenza as a “button man,” a soldier who executes an order (usually murder) after the caporegime “presses the button” (gives the order). Paulie at first proves loyal to Clemenza, so much so that Clemenza passes over other men with more experience than Gatto in order to move the latter up the Corleone Family ranks. Paulie dutifully “makes his bones” by committing a first murder for the Family, and in exchange, Clemenza gives Paulie a percentage of the Family’s bookmaking income and a fake union payroll slot. Despite the trust Clemenza places in him, however, Paulie betrays the Corleones by taking secret payments from Sollozzo and calling in sick during bodyguard duties, leaving only the feeble Fredo to protect Don Corleone. Paulie’s betrayal leads directly to the near assassination of the Don. When Sonny discovers that Gatto has turned traitor, he orders his death. Clemenza and his new button man, Rocco Lampone, drive Paulie to a deserted road and shoot him in the head.
