Most people seemed to know last week’s quote, which was from Buffy the Vampire Slayer episode 2×16 “Bewitched, Bothered, and Bewildered”:
Amy: Oh, I don’t know, Xander. Intent has to be pure with love spells.
Xander: Right. I intend revenge. Pure as the driven snow.
This week’s difficulty: Easy, 1 point.
