In my drama class at school, I often find myself playing gangsters(as everybody knows that I belive The Godfather to be the greatest achivement of mankind). This one time, I began to recite the opening scene of Part I. I then started talking entirely in GF quotes. When I got to "You spend time with your family?", one girl said "hey..you got that from a film didn't you". Where did she think I got everything els from? Did she seriously think that "If anything in this life is certain....." came of the top of my head?
I often quote from The Godfather aimlessly when I'm not doing anything.
Around others I often say "You talkin to me?" That quote suits just about any situation, and is great for when you can't think of anything els to say.
