When does Loki swear in The Avengers?

In "The Avengers," Loki swears during a scene in Stuttgart, Germany, after he confronts a crowd and declares, "I am Loki of Asgard, and I am burdened with glorious purpose." He uses a more explicit curse when he says, "You were made to be ruled. In the end, you will always kneel." This moment emphasizes his arrogance and disdain for humanity.
