Amy: Okay. Well, what I think is going on here is you have a pathological need for closure.
Sheldon: Oh, that's nonsense. I mean, you tell me stories about your day all the time. I don't care how they end.
Amy: You know, I might be able to help you with this. There's a whole field of behavioral neuroscience that examines ways to retrain your neural pathways so stuff like this bothers you less.
Sheldon: Yeah, but I just told you, I don't have a problem with closure.
Amy: You sure about that?
Sheldon: Oh, quite sure. (Amy performs a knocking pattern but stops before completing it. Sheldon finishes it off.) That proves nothing.

Leonard: I think you'll like the next one better. All the cheerleaders are suffering from an evil curse.
Penny: Oh. Well, that's like my high school, too. But instead of a curse, it was crabs.

Amy: Missed one. Now your wish can't come true.
Sheldon: Lucky for you because I wished you were dead.

Sheldon: Oh, dear. Penny, have you been recording shows on our DVR again?
Penny: No.
Sheldon: Answer honestly. This is not a trial. That'll come later.

Howard: Listen to me, if she's writing about your relationship, use it to your advantage. Rig the game.
Raj: Well, that doesn't seem fair.
Howard: Is it fair that girls like confident, normal guys more than nervous weirdos?
Raj: No, it's not. I've always thought that was unfair.

Raj: I broke down and read Lucy's blog. In one of the entries, she said when we first met I struck her as a little feminine.
Howard: Just a little? That's great.

Howard: Keep reading. What does it say?
Raj: No, no, I don't know if I should. If she wanted me to know about her blog, she would've told me. It's almost like I'm reading her diary.
Howard: It's exactly what it's like. Keep reading.
Raj: No, this is creepy.
Howard: Oh, I think we were looking at creepy in the rear-view mirror when I put up that camera.

Raj: I was Googling that girl I've been dating, and I found her blog.
Howard: Cool. Anything juicy?
Raj: She said she recently went on a date with a guy named Roger? And he's Indian? And he's an astrophysicist, too?
Howard: You know what's going on, don't you?
Raj: Mummy was right. American girls are sexually voracious devils.

Sheldon: Tic-tac-toe can only end in win, lose or draw, none of which will deny me closure. Especially since I'm about to win. (Amy wipes the board clean.) But we didn't finish.
Amy: Exactly. How does that make you feel?
Sheldon: The same way any normal person would. I feel like I want to peel off my own face and tear it in two and then again and again until I have a handful of Sheldon-face confetti.
Amy: And thats exactly the feeling we want to address with this course of treatment.
Sheldon: Or you could pitch in, grab a nostril and help me get this face off.

Sheldon: That show ended with all the residents of New York either dead or unconscious. Oh, now I'll never know what happened.
Penny: Well, why don't you make up your own ending?
Sheldon: Oh, sure, what a wonderful idea. And after that, I'll make up my own rules of oral hygiene. You know, instead of flossing, I'll rub pudding on my gums.

Penny: See, that's the kind of passion I didn't think I had. But then I realized I'm passionate about you.
Leonard: Oh, my cute little tushy strikes again.
Penny: No, I'm serious. Look, I've always had these plans. I was gonna be in movies and live this glamorous life, and anything less than that just wasn't worth getting excited about.
Leonard: Those things can still happen.
Penny: Oh, obviously it's gonna happen. Yeah, a psychic at a bachelorette party told me so. Anyway, what I meant was, I shouldn't wait, you know? I've got you, I've got Sheldon, all these wonderful friends. My life is exciting right now.
Leonard: That's a big deal.
Penny: It is, isn't it?
Leonard: So, does that mean we get to do stuff like talk about cool shows or get dressed up in matching costumes and go to Comic-Con?
Penny: Leonard, I had an epiphany, not a stroke.

Penny: So, I was thinking how excited you get about stuff like Buffy or science or which TV remote you and Sheldon should buy.
Leonard: The Harmony One was fine. We didn't need to upgrade to the eleven hundred, which he knows is too big for my hand.

Sheldon: Why would the Chinese make our DVR record Paul Blart: Mall Cop?
Leonard: I don't know. It's a fat guy on a Segway. That's funny everywhere.

Penny: Yeah, it was fun. Kind of reminded me of my high school. But instead of vampires, we had meth heads. But both came out at night and had messed up teeth.

Amy: I've come up with a series of exercises to help with your compulsive need for closure.
Sheldon: I take issue with the word compulsive.
Amy: All I'm saying is, we live in a world where closure isn't always an op...
Sheldon: -tion. Okay. For the sake of argument, let's say I have a problem. What would be your plan for addressing it?
