Amy ruined Raiders of the Lost Ark for me, so now I'm trying to find something beloved to her and ruin that. Amy: No, I do, and if he weren't in the movie, the Nazis would have still found the ark, taken it to the island, opened it up and all died, just like they did. Amy: Really? Amy: That sounds lovely. Basically, if something came out of me, she wrote about it. Bernadette: Howard. Check it out, The Disappointing Child by Beverly Hofstadter. Howard: How about I take a bath with you and see what happens. Indiana Jones plays no role in the outcome of the story. It's on the recommended reading list for my psychology class. Leonard: Leave it alone. Leonard: Penny, come back. Leonard: Yeah, but Sheldon and Amy were having date night and they don't need me there to make it awkward. Penny: Okay. Penny: Yeah. Penny: You were wearing her bra. Raj: Okay, uh, let's try it again. Scene: Leonard's lab. Sheldon: My apologies. Sheldon: Oh, it turns out Amy's beloved Pride and Prejudice is a flawless masterpiece. So I'd like to return the favour by inviting you to watch an episode of your favourite childhood television series, Little House on the Prairie. Stuart: Sure. When you get angry, just tell me. With or without him, the Nazis find the ark, open it and die. You don't need to seek revenge.

Summary: Amy and Sheldon watch Raiders of the Lost Ark. When he asks her what she thought of it, Amy considers Indiana Jones superfluous as the story's outcome would have been the same with or without him. After spoiling the movie for Sheldon, he tries to find something Amy loves and spoil it for her. Sheldon watches Amy's favorite TV show Little House on the Prairie with her and points out historical inaccuracies. Amy, realizing his purpose, says he should just let her know if he is angry, not seek revenge. He complies; Amy apologizes. For her psychology class, Penny buys The Disappointing Child (in which Leonard's mother wrote about his childhood problems), upsetting Leonard. Penny goes out of her way to comfort him; he takes advantage of her sympathy. Howard finds out and unsuccessfully tries it with Bernadette, who tells Penny about Howard's trick. Penny now sees through Leonard and takes revenge by wearing a babydoll outfit, only to leave a pantless Leonard skyping with his mother. Meanwhile, Raj and Stuart, depressed when women checking out their newly-uploaded online dating site profiles leave no messages, realize they don't need dating sites, and decide to move on.
