Leonard: You're awful quiet, everything okay?
Sheldon: I'm concerned about Amy. She's acting a bit odd lately.
Howard: Oh, well, j-just out of curiosity, what registers as odd to you?

Sheldon: Hit it.
*Howard playing keyboards and Raj playing guitar*
Howard: (Singing) For joy and fun, there's no better manner, than to fly a pennant, flag or banner
Raj: What fills my heart, and makes my eyes moist, sending a flag, up a pole on a hoist.
Raj & Howard: Fun with Flags, Fun with Flags
Howard: Oh! Say can you see.
Raj: It's Fun with Flags.
Raj & Howard: Fun with Flags.

Amy: As you may notice, just one of the changes around here is our new house band.
*Howard plays a keyboard solo*
Sheldon: Who haven't learned their place yet.

Bernadette: Well, they finished the work early, but she's been telling Sheldon they're behind schedule.
Leonard: So, she's just been lying to him?
Penny: Well, you've lied to Sheldon.
Leonard: Yeah, but to make him leave, not to make him stay.

Amy: So, uh, what about dinner?
Sheldon: Is it me or are you purposely changing the subject?
Amy: No. And on the subject of subjects, is your use of the word "subject" the same or different as when we speak about the subject of a king?
Sheldon: I have a feeling you're still doing it. But I find that topic irresistible, so, now, in ancient Mesopotamia, the king referred to the people as his property.

Leonard: You really didn't think I'd notice my stuff was missing?
Penny: Uh, did you notice your key chain?
*Leonard goes to the door and checks his keys*
Leonard: Where's Batman?!

Raj: I'm not really a part of this, so I'm just gonna dig in.

Raj: Now that everything's out on the table, you think you two will keep living together?
Sheldon: Despite recent events, I do consider our experiment in cohabitation to have been positive.
Amy: Are you saying you'd like to live with me?
Sheldon: I'm open to the possibility.
Amy: (gasps)
Penny: Amy, b-be, b-cool.

Sheldon: If we did continue living together, would it be here?
Amy: I don't know. It could be.
Sheldon: Of course there's there's always your apartment.
Amy: Sure, sure, we could live in my apartment.
Sheldon: I hate your apartment.
Amy: Sorry, you brought it up?

Howard: This isn't complicated. Do you love Amy?
Sheldon: Yes.
Raj: Do you like living with her?
Sheldon: Yes.
Leonard: Do you know what you need to do now?
Sheldon: Apparently, figure this out on my own 'cause you guys are no help at all.

Leonard: Just hiding some stuff in your closet, don't tell Penny.

Sheldon: Are you going to confront Penny?
Leonard: Eventually, I guess. Although, I am kind of curious how long she thinks she can keep hiding my stuff without me knowing.
Sheldon: Hmm. You know, perhaps instead of confronting them, we should see how far they're willing to spin their tangled webs. Like that Spider-Man action figure that used to be on your desk.
Leonard: Oh my God, I'm going blind.

Howard: See, I've known that for weeks, but, you know, I waited till the moment when it would cause him the most pain.
