Howard: What's with the T-shirt? You working at the Apple store now?
Leonard: No, it's just something I threw on.
Howard: I know all your shirts. That's not one of them. You were pretending to work at the Genius Bar to pick up women, weren't you?
Leonard: Yeah. Turns out, they guard the iPods, but they don't guard the shirts.
Howard: So, how'd it go?
Leonard: It was going well. I was showing this super hot girl how to boot up in Safe Mode. The manager got suspicious, and, well, long story short, they really do have a little jail in the mall.

Howard: Just FYI, don't try to go back with a fake moustache. I mean, they may not really be geniuses, but they see right through that.

Leonard: Well, I'm off to meet Bernadette's friend. How do I look?
Sheldon: As if one of the plants from Invasion of the Body Snatchers duplicated you in every way, only with an absurd amount of hair gel.

Leonard: What are you working on?
Sheldon: I'm removing my digital footprint from the Internet so Amy Farrah Fowler can't find me and compel me to meet her mother.
Leonard: Ah, you're going off the grid.
Sheldon: Exactly.
Leonard: The old Unabomber approach. Kudos.

Amy: I believe a misunderstanding may have occurred when I asked you to meet my mother.
Sheldon: No misunderstanding. I've learned what that request actually means, and I don't want to be joined to another object by an inclined plane wrapped helically around an axis.
Amy: In what way are you screwed?

Amy: I trust this clarification allows us to return to boy-slash-friend-slash-girl-slash-friend status.
Sheldon: Of course. Would you like to join me for Chinese food?
Amy: Sheldon, please, you're suffocating me.
Sheldon: My apologies. Good night, Amy.
Amy: Good night, Sheldon.
