S15E14 - The Ziff Who Came To Dinner.
Homer took Bart and Lisa to the theatre to see the movie Re-DEADNING (a horror movie) and the kids were very scared.
Lisa: Dad, I don't like this movie. Can we go home?
Homer: Oh honey, don't be scared. Look, they kill the evil doll.
Homer: Well, what do you know? It's unkillable.
Homer: Honey, can daddy rest his soda on your head?
Homer: That's my girl.^^
Awwwww, Lisa is so cute when she's scared.
