I'll chop the hands off the next man who calls me bastard!
Source: Episode 3x4, "And Now His Watch is Ended"
Note: Character has just been insulted by the Night's Watch men he is sheltering, who have become fed up with the meager food they've been given and Craster's remarks about their wounded. Karl, a Night's Watch brother finally pushed beyond the breaking point, deliberately calls character a bastard again. Craster lunges at Karl, but is fatally stabbed by him.
