Episode Notes

  • The title refers to Sheldon hiring Stuart to stand in line at the cinema for him as he tries to patch things up with Amy.

> Sheldon's Knock

Sheldon performs his ritualistic knock on Penny's apartment door when he goes to apologize to Amy for sending Stuart to spend time with her while he waited in line at the movies. Earlier, Bernadette wondered whether Sheldon had come to apologize to Amy when there was a knock at the door, but it turned out to be Stuart sent by Sheldon to apologize. Bernadette didn't seem to notice that Stuart's knock on the door was not Sheldon's characteristic knock.

Quotes (48)

Leonard: When's the screening?
Raj: Uh, it's tonight, but it's first-come, first-served, so we should probably get there early and wait in line.
Howard: Let's do it.
Leonard: Penny's busy with my mother, so Im in.
Sheldon: Oh, bad news. Amy's making me go shopping with her later, so looks like none of us can go.
Leonard: You do realize were allowed to have fun without you?
Howard: In fact, that's usually the trick to it.

Sheldon: *Knock, knock, knock* Amy. *Knock, knock, knock* Amy. *Knock, knock, knock* Amy.
Amy: Come in.
Sheldon: Hello, everyone. Oh, Beverly, good to see you. I'd love to chat, but there's a line that could start moving any minute, so let's do this. Amy? A proper apology requires three steps. Step one, an admission of wrongdoing. Amy, I was wrong. Step two, a promise never to repeat said action. Amy, that action will never be repeated, and that's a promise. Step three, an earnest request for forgiveness. Amy, I hope you can forgive me. And I hope you do it right now, 'cause there's an Uber waiting downstairs, and I don't want to repeat this apology nonsense with my driver Ganesh.
Amy: Fine.
Sheldon: Oh, thanks, you're a peach. Beverly, we'll catch up soon. Bernadette, it was a pleasure as always. Penny, you have spinach in your teeth.

Penny: Helium.
Sheldon: Yes.
Penny: Yes.
Sheldon: Taylor Swift.
Penny: Yes. Pi.
Sheldon: Yes. Kardashian.
Penny: More specific.
Sheldon: Khloe?
Penny: Yes.
Sheldon: See, I remembered because if it looks like Kim it's Kim, if it looks kind of like Kim it's Kourtney, and if it looks nothing like Kim it's Khloe.

Penny: Oh, that's a Venn Diagram, and I remember because I thought to myself, "Venn is he gonna stop talking about this diagram?"

Penny: You really want me to pick up your mother all by myself?
Leonard: Hmm, I just feel like it would be a good chance for you to bond.
Penny: Or a way for you to avoid her?
Leonard: I don't know what he's putting on those cards, but you are smarter than ever.
