Sheldon: What happened to me, Amy? Years ago I was completely disengaged from my feelings. I'd say it was a happier time, but I was disengaged from my feelings, so who can tell?

Amy: I don't know how to help you. You know, feelings are a part of life.
Sheldon: They didn't used to be. You and Leonard and Penny, you all poisoned me with emotions. I was like the Tin Man, perfectly content until that evil Wizard gave him a heart.
Amy: I don't think that was the point of the movie.
Sheldon: Fine, then I was like Pinocchio before that jerk Geppetto went and made him a real boy.
Amy: There you go.

Penny: Hang on. Wait, you actually think it's 2003?
Sheldon: No, just because I'm living my life like it was 12 years ago doesn't mean I'm delusional.
And since it is 2003, I don't know who you are, so please exit the premises before I call the police on my stylish new flip phone.

Penny: Are you doing okay?
Leonard: I guess. I'm just, you know, worried about Sheldon.
Penny: Well, come on, he's a grown man in his 30s pretending to be a grown man in his 20s. He's fine.

Penny: What else can you do? Move back in with him?
Leonard: No, of course not. I just feel bad.
Penny: Well, so do I, but don't you want to live with your wife and set the thermostat to whatever you want? And have your body tell you when it's time to go to the bathroom? You know, not a schedule slipped underneath your door every morning?
Leonard: I did like that he had the weather on it.

Penny: Trust me, this is the right thing.
Leonard: I know. And it's not like we're abandoning him.
Plus, we can FaceTime him whenever we want, you know, once iPhones are invented in his universe.

Bernadette: Hey, if you're open to living with someone great, I'll give you $1,000 to take Stuart.
Amy: You really should've gone on the Internet and checked how long that kind of thing lives before you got one.
Bernadette: I'm sorry. I just thought you might have a pasty, weirdo-shaped hole in your life.

Raj: "Thor and Dr. Jones. Thor and Dr. Jones. One runs from Loki, the other runs from stones."
So, what do you think?
Emily: Wow.
Raj: Runs from stones means that-that big boulder, but I couldn't rhyme anything with boulder.
Emily: Colder, shoulder, soldier, folder.
Raj: Right, yeah, right.

Raj: I'm telling you, dude, the song has no groove. You can't dance to it.
Howard: Who cares? I thought the whole point of Footprints on the Moon was to write songs that make people think.
Raj: You can do both, like Michael Jackson's "Billie Jean". While you're dancing you're thinking, like, "Darn it, whose baby is it?"

Sheldon: Just give me one minute, and I'll get started on a new Roommate Agreement.
Yeah, nothing from Pratt. We're good.

Raj and Howard: Indy' whip snapped. Thor's hammer missed. It was Avenger vs archeologist. Indy held his ground. And straightened his fedora. Thor said, "That's a nice look In 1944-a".
Thor and Dr. Jones. Thor and Dr. Jones. One plays with lightning. The other plays with bones. Thor and Dr. Jones. Thor and Dr. Jones. Thor and Dr. Jones. One plays with lightning. The other plays with bones.
Stuart: Play something we can dance to.

Sheldon: What a wonderful day, thank you.
Penny: Oh, we're glad you had fun.
Sheldon: Blue Icees and a trip to The Container Store? It's like I died and went to the post-mortem, neuron-induced hallucination commonly mistaken as heaven.

Penny: Sheldon, please, we already feel bad about this.
Sheldon: You know what they don't sell at The Container Store? Something large enough to contain my disappointment.
Although, if anyone did, it would be them.

Leonard: Buddy, I know me moving in with Penny feels like a big change, but it's not.
Sheldon: How can you say that? Amy's gone, and you two are married now, so it's only a matter of time before you're gone, too.
Penny: Okay, you don't know what's gonna happen.
Sheldon: No, I do. Eventually you'll want more space and you'll move into a house. And then instead of dinner a couple of times a week, it'll only be a couple of times a month. And then it'll only be on special occasions, like when Bernadette divorces Wolowitz.
Or-or-or like when Koothrappali's weird girlfriend admits where she buried his body.
Or Amy's wedding, where she's marrying someone better than me.

Leonard: I still don't understand why you bought that pill caddie. You're a young man.
Sheldon: Age is a state of mind, Leonard. In here I'm 90.
