Tonino Sandrelli Murders Gyp (Season Three, Episode Twelve)
Talk about stabbing someone in the back – literally. One of the last few men remaining loyal to sadistic gangster Gyp Rosetti, Tonino Sandrelli is discovered hiding out at the Artemis Club by Nucky and Eli, who have taken their city back from Gyp's unstable clutches. When Tonino meets up with Gyp at the beach the next morning, he listens to his employer talk about moving their operations out west. But as Gyp takes a long, relaxing piss, singing the 1920s tune "Barney Google With the Goo-Goo Googly Eyes," he stops mid-lyric, as Tonino plunges a knife in his back. As Gyp turns around, Tonino finishes him off with a stab to the chest. When the deed is done, Tonino walks up the road to a waiting Nucky and Eli. Turns out Nucky spared Tonino's life only if he promised to take out Gyp – and to never show his face in Atlantic City again.
