Leonard: First thing tomorrow morning, we're back at it.
Raj: Without me.
Sheldon: I hope his character doesn't make it into the movie; he's kind of a bummer.

Sheldon: Who leaves their bike in the hallway? You know, if I knew how to ride one, I'd steal it.

Amy: Wait, are you saying if we combine my experiment with your calculations, we can determine the precise moment in time when the wave function collapses?
Sheldon: It could be the most inspired combination since I mixed red Icee into my blue Icee. It was like drinking 2/7ths of the rainbow.
Amy: Sheldon, this is really interesting.
Sheldon: Yeah and this one won't stain my teeth purple.

Raj: I'm the son of a gynecologist. I could be helpful.
Bernadette: It would help if you stopped telling me I have a textbook cervix.
Raj: The polite response is, "Thank you for noticing."

Sheldon: At our age, why don't we call it man's night?
Leonard: Because we just spent our allowance on comic books.

Sheldon: Two years ago I got my driver's license.
Amy: What? Why didn't you say anything?!
Sheldon: I like being chauffeured around. It makes me feel important.
Amy: So when I got up at 4:00 AM to drive you across the desert to an antique train museum, I didn't have to?
Sheldon: No, you didn't. But keep in mind, I felt extremely important.

Penny: Pink wine and pizza bagels? It's like eighth grade all over again.

Penny: Hey, have you ever heard of the Van Nuys Comic-Con?
Leonard: Yeah, it's a dinky little convention where they sell collectibles and get sad D-list celebrities to appear. Why?
Penny: I got asked to sign autographs there.
Leonard: That's awesome! Is this for Serial Ape-ist?
Penny: Well, it could be for the monkey movie. It could be my hemorrhoid commercial. The list does not go on.

Bernadette: It's okay, I'm just being emotional about this. Can you not tell Howard?
Stuart: Well, don't you think it'd be healthier if you told him what's going on with you?
Bernadette: Don't you think it'd be healthier if you had your own apartment, grown man?
Stuart: Your secret is safe with me.

Penny: So, Bert, you were telling us how you updated your profile?
Bert: Right. I wasn't getting any responses, and then I added, "Recent $625,000 MacArthur grant winner", and five minutes later, I met my soul mate.
*Amy goes to the hallway*
Amy: I was wrong. You can come back in.

Raj: He doesn't just look like C-3PO, now he walks like him.

Lucy: Can I just say something? Going out with Raj was one of the best things that ever happened to me.
Raj: Yes, I'll take you back.
Lucy: It's like I needed to go through that experience to know what exactly I don't want in a man.
Raj: That's hard to hear, but I'll still take you back.

Bernadette: This is ridiculous. The doctor knows what the baby is, the ultrasound tech knows, Raj knows, his Grey's Anatomy online fan group probably knows.

Leonard: Here's the hotel room we all share.
Penny: Well, you and I would get our own room, right?
Leonard: Every hotel is booked. But, yeah, see this space here between Sheldon's feet and my head? That's where you go.
Penny: Well, it's no different than when Sheldon used to climb in bed with us during a thunderstorm.

Amy: Look, we can't just throw away Penny's stuff, but we can ask if she wants any of it back.
Sheldon: You know, I wonder how she feels about all this artwork.
Amy: Well, I'm sure she misses this one. I mean, it's the greatest gift I've ever given anybody.
Sheldon: It truly does capture the beauty of your friendship with Penny.
Amy: It may have appreciated in value. The artist killed himself shortly after painting that.
