Snake, I see where you're coming from, but to be honest I think Tony's mouthing off to Richie in that scene is by pure frustration. Whenone is frustrated, one's mind goes completely blank, and I think in this case Tony was lost for words to add emphasis. I am actually speaking from experience here, as I often get frustrated to the point where I can repeat a word--much to the laughter of my friends, at my expense of course.
