Sheldon: Some news of our wedding. I have sent you all a "save the date" e-mail.
Penny: Oh, exciting. You guys picked a date?
Sheldon: Better. I picked 80 dates. And I need you to save them all until we narrow it down.

Leonard: When did we get a wall safe?
Sheldon: When there was no more room in the floor safe.
Leonard: When did we get a floor safe?
Sheldon: When we got the security camera.
Leonard: There's a security camera?
Sheldon: Aquaman, protecting your home since 2012.
Penny: Oh, my God. We've done things on that couch.
Sheldon: Yeah, you don't have to tell me.

Bert: Hey, Sheldon.
Sheldon: I've been thinking about it, and I suppose I could help you with your research.
Bert: What changed your mind?
Sheldon: Bert, I'm a gift horse. Don't look me in the mouth.

Adam Nimoy: What was it about Spock that appealed to you?
Sheldon: I think the same thing that appeals to people everywhere, the dream of a cold, rational world entirely without human emotion.
Spock came from a planet governed only by logic.
You know, on Vulcan, when your brother asks, "Why are you hitting yourself?" The answer is, "I'm not. You're moving my arm." To which he says, "fascinating." And then you both watch educational television.

Raj: And you know we get to name it.
Sheldon: We better choose a name no one can make fun of. Sir Frederick William Herschel didn't do Uranus any favors.

Sheldon: Read it back to me?
Leonard: Oh, hang on. "Yes, one might question the $20 billion "to build and run the Large Hadron Collider, but on the other hand..."
Sheldon: Okay. Um, oh, oh! "On the other hand, contrary to predictions, the collider didn't create a small black hole that devoured the Earth and life as we know it." So, money well spent.

Leonard: Hey, I made French toast sticks.
Sheldon: On oatmeal day?
Leonard: Ah, I also made oatmeal.
Sheldon: Ooh, that's a lot of carbohydrates for a man on the prowl. You know what? You eat it. You're married, it doesn't matter what you look like.

Sheldon: I've just discovered I don't have enough room on my hard drive for a Linux partition, so you and I are going to perform a full backup, re-initialize and then re-install all my operating systems.

Sheldon: Studies are shown that performing tasks such as eating, talking on a cell phone or drinking coffee while driving reduces ones reaction time by the same factors as ounce of alcohol.

Penny: You know, they have a really nice bar over at the Olive Garden.
Sheldon: I don't like the Olive Garden. They treat me like family.

Amy: And this is Dr. Gundersen from Stockholm.
Sheldon: Ah, Sweden. Home of my favorite Muppet and second-favorite meatball.
*Dr. Gundersen and Amy look blankly at Sheldon*
Sheldon: Okay, the Nordic reputation for a lack of humor is well founded. Boy, is his name Gundersen or No-fun-dersen?

Amy: Hello.
Sheldon: Hi.
Amy: Ready for the aquarium?
Sheldon: I am. You know, and in an effort to reduce awkwardness as we learn how to function as friends, I printed out a list of safe topics for polite conversation.
Amy: If that makes you more comfortable.
Sheldon: If there were a list of things that make me more comfortable, lists would be on the top of that list.

Raj: Oh, you bought cookies?
Sheldon: Yes, fig newtons. I was going to ask which scientist both helped to discover calculus and had a famous cookie named after him. And then after someone said Newton, I was going to tell them they're wrong. The cookies are named after a town in Massachusetts. And then I'd throw the cookies away.

Raj: Hey, Sheldon, guess what I've heard today.
Sheldon: I'd imagine you heard any number of things today. When you arrived at work, you undoubtedly heard: Hello, Raj; How are you, Raj; and given you're wearing a new sweater vest, you may have heard: "New Sweater Vest" and possible, though less likely "Nice Sweater Vest."

Sheldon: Here comes the Embarrassment Express. It stops at Fraudville, Wonder-Blunder-Berg and Kansas City, because it's a hub.
