Sheldon: We might as well stop. It's a stalemate. You're beating me at tetris, but you've got the upper body strength of a Keebler Elf.

Penny: I want to talk to you.
Sheldon: What would we talk about? We've no overlapping areas of interest I'm aware of,. and you know I don't care for chit-chat.

Sheldon: Given our new found intimacy, I'd say we have some hard choices to make.
Penny: Like what?
Sheldon: Gary Con. Do we fly or drive? Do we wear costumes? And if so, who gets to be Gary?

Penny: This is kind of creepy.
Sheldon: We're not supposed to talk during this part.
Penny: Sorry.
Sheldon: This is kind of creepy.

Penny: Do you want to stop? I know you have trouble with eye contact.
Sheldon: Well, you have a brown fleck in your right iris that looks like a Formula 1 race car, so I'm just concentrating on that. Plus it's easier around people I'm comfortable with.
Penny: Oh, sweetie, I'm comfortable around you, too.
Sheldon: Of course you are. I'm warm and soothing. I'm like a human bowl of tomato soup.

Penny: Just thinking about the day I met you and Leonard.
Sheldon: It was a Monday afternoon. You joined us for Indian food.
Penny: Can you believe it's been eight years?
Sheldon: And you're still eating our food.

Sheldon: I think it's safe to say you're not in love with me and I'm not in love with you. And psychology has once again proved itself the doofus of the sciences.

Penny: If you were to die this evening with no opportunity to communicate with anyone, what would you most regret not having told someone?
Sheldon: So it would be today? Huh. Well, I suppose there's something satisfying about dying on my birthday.
Penny: Today's your birthday?
Sheldon: Yes.
Penny: Well that's always been a secret. Not even Amy knows.
Sheldon: Well, I don't enjoy presents. And the thought of people jumping out and yelling surprise fills me with more dread than the words "George Lucas Director's Cut.

Penny: That's so funny. I never would have pegged you for a Pisces.
Sheldon: You're making it difficult to love you right now.

Sheldon: You may not be as academically inclined as are we. Yes, that's how you say it. But you possess an intelligence I envy, which leads me to my answer. I would choose the ability to read people's minds.

Penny: What's yours?
Sheldon: I wake up. I enjoy some french toast with butter and syrup. Then a wormhole opens and whisks me millions of years into the future, where my towering intellect is used to save the last remnants of mankind from a predatory alien race.
Penny: Interesting you didn't mention Amy.
Sheldon: Who do you think made the french toast and syrup?

Sheldon: As a Texas gentleman, I'm inclined to say ladies first. Although, I'm concerned that level of politeness and charm may make you fall in love with me before the test even begins.

Sheldon: As much as I'd love to meet Euclid, inventor of the geometric proof, he probably wore sandals and I can not look at toes during dinner.

Sheldon: Oh, I know, the person I'd most like to have dinner with is myself.
Penny: You sure that's your choice, because I've had that dinner.
Sheldon: Well, I haven't. And although they say never meet your heroes, I just don't see how I could disappoint.

Sheldon: Who would you choose?
Penny: Robert Downey, Jr.
Sheldon: Oh. I didn't think of Iron Man. You know, maybe after myself and I have dinner, we could meet you two for dessert.
