At the end of the episode, Dean Munsch says, "They also say that 'Hell hath no fury like a woman scorned'." This is one of the most misquoted lines in English literature. The original line the misquote is based on is from the 1697 play The Mourning Bride, Act iii. Scene 8, by William Congreve (1670 - 1729). The original line is "Heaven has no rage like love to hatred turned, nor hell a fury like a woman scorned.", or, as Congreve originally wrote it, "Heav'n has no Rage, like Love to Hatred turn'd, Nor Hell a Fury, like a Woman scorn'd"
