Quote from Carla in The Belles of St. Clete's
Norm: What happened? Carla: It's her. It's the Evil One. Sam: Where? What? Carla: Over there at table five. Cliff: Oh, the little old lady? Carla: Drusilla Dimeglio. She was the principal at St. Clete's School for Wayward Girls. We all hated her guts. She used to do these mean, spiteful things to us. Oh, I swore vengeance on her, but she retired before I could do anything. Now, twenty years later, there she is. Sam: It's been twenty years. Are you sure it's her? Carla: Well, there's one way to make absolutely sure, Sam. She has my teeth mark on her left ankle.
