Episode Quotes

Sheldon Cooper: What is your problem?
Amy Farrah Fowler: It's Valentine's Day. We're supposed to be having a romantic weekend.
Sheldon Cooper: Oh really? Because I remember you saying that trip was going to be something we could both enjoy. Did you really mean that or were you just trying to trick me?
Amy Farrah Fowler: Fine, it's true. I deserve romance and I didn't know how else to make it happen.
Sheldon Cooper: Well, if you want romance, let's have romance. Oh, look, there's wine. [Takes Amy's wine glass and drinks] Grape juice that burns. Um, let's now gaze into each other's eyes. [Looks at Amy's eyes] You blinked, I win.
Amy Farrah Fowler: Sheldon.
Sheldon Cooper: What's next? Oh, kissing's romantic. [Amy doesn't believe him, gets kissed and enjoys it. So does Sheldon]
Amy Farrah Fowler: That was nice.
Sheldon Cooper: Good. Um. The conductor said if I come back to the engine room he'd show me how to bring the train through a crossing.
Amy Farrah Fowler: OK, have fun.
Sheldon Cooper: Do you want to come with me?
Amy Farrah Fowler: Really? I do.
Howard Wolowitz: A world I don't want to live in. Seriously I don't want to live in this world.
Sheldon Cooper: We've only been dating three years. If we share a room people might talk.


  • Goof (continuity error): When Penny and Leonard are waiting for the vet, Penny's arms are either crossed with the right arm over the left or the left arm over the right depending on the camera angle.
  • Goof (errors made by characters, possibly deliberate errors by the filmmakers): When Leonard suggests having sex in Sheldon's spot, Penny claims that it is "the least sexy thing anyone has ever said to me." However, in season 3's episode The Pirate Solution, Penny is the one who suggests making out in Sheldon's spot.
  • Goof (continuity error): SPOILER: When Sheldon returns from Napa Valley and reveals the events of the weekend, Leonard presses for more details. Sheldon states that he kissed Amy Farrah Fowler on the lips, and then offers, "Amy's lips tasted like the brownie we had for dessert." Several scenes prior however, Amy is chatting with Bernadette and Howard over dessert, and it appears to be cheesecake. There's no chocolate in sight.
  • Goof (continuity error): After Amy mimes shooting herself in the head, she collapses on the table and makes the wine in the glasses vibrate. In the next shot, the wine is still.
  • Goof (continuity error): When Bernadette gets up from dessert to get Sheldon away from Eric, Howard clasps his hands together. In the next shot, showing Bernadette walking away, his hands are spread out on the table.


  • Sheldon's question about the type of couplers shows how little he really knows about trains. Couplers of the type he describes have been outlawed since 1893 for safety reasons, and the cars are all-steel construction, indicating they were built around 1910 or later. Also, these coupler types (and the one Eric describes) all have different and distinct appearances, so a quick glance at the exterior of the cars would have clearly indicated what type they were.
  • Title Reference: Sheldon feels that Amy is trying to manipulate him into romance while having dinner aboard a vintage train.
  • SPOILER: First episode where Sheldon kisses Amy on the lips.
