A few hours later, the pair is arguing about Casablanca.
We thought everyone pretty much agreed on the awesomeness of that movie, but Harry and Sally have found a point of contention: they totally disagree on the ending.
Sally thinks the ending makes sense—she wouldn't want to be married to some guy who owns a bar in Casablanca, even if that guy happened to be Humphrey Bogart.
Harry thinks that makes no sense. Who wants to live in a passionless marriage?
Oh, wait. Harry knows why Sally likes the ending: she hasn't had any good sex in her life. Well, that's a big assumption.
Sally begs to differ, and accidentally announces that fact to the diner they've just walked into. It's awkward.
Harry pushes it. With whom did she allegedly have such great sex?
Sheldon, that's who. Harry's skeptical that a guy with a name like Sheldon could have great sex with Sally. (Sorry, Sheldons of the world. The views expressed by Harry to not represent those held by Shmoop. Or Sally, for that matter.)
The two are interrupted by a waitress, who takes their orders.
Harry wants a "number 3," while Sally's order is a bit more… persnickety. She's got all kinds of very specific requests.
Harry looks at her like she's got an elephant trunk growing out of her forehead.
He wants to know why she broke up with Sheldon.
After demurring a bit, Sally tells him it was because "he was very jealous, and I had these days-of-the-week underpants." It's really only something you can understand if you watch the scene, so here you go.
