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.
Yvette: I should have been a dentist.
Penny: Happy Valentines Day!
Leonard Hofstadter: Flowers and chocolates? You trying to get me out of my panties?
Penny: Don't be surprised if you find five chocolates missing and three gross coconut ones with a bite taken out. Came that way when I bought it.
Leonard Hofstadter: I got you a little something too. [Gives Penny a jewelry box]
Penny: Oh my. Jewelry. [Opens box] Oh, my God. Lakers' tickets!
Leonard Hofstadter: It gets better. Instead of me, you can take someone who will actually enjoy it.
Penny: Aww! You are the best boyfriend ever!
Leonard Hofstadter: Thank you, seriously, please don't make me go.


  • Goof (revealing mistake): In the vet's office, when Raj says his line about being Leonard and Penny's worst nightmare, Yvette can be seen biting her lip to keep from laughing.
  • 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."


  • Title Reference: Sheldon feels that Amy is trying to manipulate him into romance while having dinner aboard a vintage train.
  • This is the 150th episode of the series.
  • 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.
  • SPOILER: First episode where Sheldon kisses Amy on the lips.
