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.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Josh: So, I have to ask, was the robot sexy?
Howard: It was actually just a mechanical hand.
Josh: 'Cause that's all you need, right?
Howard: You are my brother.

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Stuart: Anyone else need anything before I go?
Howard: I'll give you a dollar if you make fun of Raj.
Stuart: That's mean.
Howard: Five.
Stuart: You look like Tigger if Tigger looked like a jackass.
Howard: Uh, if you ever need a reference or anything, just let me know.

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?"
