From the movie Full Metal Jacket, directed by Stanley Kubrick
Running his flashlight across the room JOKER Sees PYLE sitting on a
toilet, loading a magazine for his M-14 rifle.
PYLE looks up at JOKER and smiles. It is a frightening smile.
PYLE: (strange voice) Hi, Joker.
JOKER stares at PYLE for a few seconds.
PYLE has quite clearly snapped.
JOKER: Are those ... live rounds?
PYLE: Seven-six-two millimeter, full metal jacket.
PYLE smiles grotesquely.
