“Donnie Brasco: You think I'm a rat...? Lefty: [to Donnie's while in his car, before putting a loaded revolver to his head] How many times have I had you in my house? If you're a rat, then I'm the biggest mutt in the history of the Mafia.”
— Paul Attanasio, Donnie Brasco / Joseph D. 'Joe' Pistone, Johnny Depp, imdb.com
