Tropes
- Groin Attack: Downplayed. Leonard pulls his groin while dancing with Amy.
- Rail Enthusiast: Sheldon spends the day at the train model store, coming back home giddy as a schoolgirl.Sheldon: Woo-woo! It's official! I'm an HO trainiac!
- That Came Out Wrong: The way Leonard phrases how he spent the day with Amy, it's no wonder Sheldon reacts the way he did.Leonard: I had a lot more fun with Amy than I thought I would.
Sheldon: What exactly do you mean?
Leonard: Well, turns out she really knows how to help a guy loosen up and have a good time. Although, truth be told, my groin is a little worse for wear. [Sheldon hits him in the shoulder with a model train] Ow! Why did you do that?
Sheldon: To send you a message. She's not for you.
Leonard: What?
Sheldon: Not! For! You!
