The strategy on YouTube is to string out your stories so as to generate more views, so Sammy's talking about things he only heard about. Last episode he talked about how Roy DeMeo cut a bullet out of Nino Gaggi's neck which wasn't what happened. Some of the shorts Sammy does on YouTube are bullshit but some are interesting too and provide insight into some of the old school guys like Joey Gallo, Dellacroce, Castellano and Toddo Aurello.
