You know, Dirty Harry Callahan is iconic and all when he says that, but when I show this to my high school class, I sho clips of Americana periodically, I show it from this point and it breaks them up:
From Wikip:
“While in a local diner, Callahan sees a bank robbery in progress and, alone with his revolver, he kills two of the robbers and wounds a third, challenging the man lying near a loaded shotgun:”
He leaves the diner, but he’s eating his lunch and he’s pissed at having to interrupt his lunch for this lowlife in action. He’s got his gun out and hea’s taking a bite out of his sandwich while crossing the street.
And the annoyed sneer.
Just great.
