Episode Quotes

Amy Farrah Fowler: Why do I even try?
Bernadette Rostenkowski: I'm going to fix this right now.
Howard Wolowitz: OK. Just make it look light an accident.
Bernadette Rostenkowski: Excuse me. You at a Valentine's dinner with your girlfriend. Now get back over there and be with her.
Sheldon Cooper: You're right. That was insensitive of me. I have to got back to my table now. You should join us.
Eric: All right.
Bernadette Rostenkowski: Great. Now there's two of them.
Yvette: Are you the owner?
Raj Koothrappali: Owner, father, and if something happens to her your worse nightmare!
Raj Koothrappali: You do whatever it takes to save her life. If she needs any new organs I'll buy any dog necessary and scrap them for parts.


  • 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.
  • Goof (errors made by characters, possibly deliberate errors by the filmmakers): The locomotives used on the Napa Valley Wine train were built by the American Locomotive Company, commonly abbreviated to "Alco." However, Amy calls the company "Alcoa."
  • 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 (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): 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.


  • SPOILER: First episode where Sheldon kisses Amy on the lips.
  • 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.
