Sheldon: Can you believe they said I was just like Edison? Yeah, and in front of a lady, no less.

Amy: I know we only have coitus on my birthday, but I don't know if I can wait until midnight.
Sheldon: Oh, well, you'll be glad you did. Everyone knows the best foreplay is rigid adherence to a strict schedule.

Leonard: You having a good day?
Penny: No, I missed an audition because my computer broke, and I didn't get the e-mail. Would've been a perfect part for me.
Sheldon: Was it waitress who ignores her customers? Because that's the role you were born to play.
Penny: Shut up and eat your burger.
Sheldon: Actually, it's a turkey club.
Penny: Didn't you order a burger?
Sheldon: I did, and yet here we are.

Sheldon: *knock knock knock* Penny! *knock knock knock* Penny! *knock knock knock* Penny!
Penny: Sheldon, go away. I'm making a video.
Sheldon: Oh, I'm sorry. I'll come back when you're alone.

Raj: What, y-you stole our Bitcoin?
Sheldon: Oh, calm down. All I did was sneak onto your computer and download your Bitcoin onto a flash drive.
Leonard: What?
Sheldon: I'm not keeping it. I just wanted to watch you sweat.
Howard: If you want to watch him sweat, walk up a flight of stairs with him.
Sheldon: I've waited seven long years, but it finally happened.
Leonard: Where's our money?
Sheldon: That's the best part. It's on the Batman flash drive on your key chain. You've had it in your pocket all along.
Leonard: Sheldon I lost that key chain years ago.
Sheldon: Really? D-D-Did you look under things?

Sheldon: All right, Amy, you're up. Next decision.
Amy: Come on, first dance! Come on, first dance!
Sheldon: (runs computer randomizer) Invitations! Oh! That's a good one. Just a suggestion, hologram projected out of R2-D2.

Amy: Your turn.
Sheldon: (runs randomizer) Ring bearer! Oh boy, I'm so glad that R2-D2 is still available.

Sheldon: Neither of them will be the actual cake. I'm just using it as a bargaining chip to get Amy to agree to the whole wedding party getting rings and us getting one ring to rule them all.

Sheldon: You know, in the future, when we're disembodied brains in jars, we're going to look back on this as eight hours well wasted.
Raj: I don't want to be in a jar. I want my brain in an android body. Eight feet tall and ripped.
Howard: I'm with you. I just have to make sure if I'm a synthetic human I'd still be Jewish. I promised my mother.
Raj: I suppose you could have your android penis circumcised. But that's something your Rabbi would have to discuss with the manufacturers.
Sheldon: Not to mention you'd have to power down on Saturdays.

Leonard: Okay, if I may drill down to the bedrock of my question, why did you throw it out?
Sheldon: Because I have no interest in standing in the Rose Room of the Pasadena Marriott in front of a group of judgmental strangers, who wouldn't recognize true genius if it were standing in front of them giving a speech. Which, if I were there, it would be.

Leonard: You cannot possibly be that arrogant.
Sheldon: You continue to underestimate me, my good man.

Penny: Okay, so Kim, the night manager, went on maternity leave, and her husband's name is Sandy, right? So get this, her replacement is a woman named Sandy whose husband's name is Kim.
Leonard: Wow!
Penny: I know. What are the odds?
Sheldon: Easily calculable. We begin by identifying the set of married couples with unisex names. We then eliminate those unqualified for restaurant work: the aged, the imprisoned and the limbless, for example. Next we look at-
Leonard: Sheldon! It's an amazing coincidence, can we leave it at that?
Sheldon: I'm sorry. Ooh, Penny, it's as if the Cheesecake Factory is run by witches.

Wil Wheaton: Hello, Sheldon. I suppose you've come here to tell me that you've moved me to your super secret enemies list.
Sheldon: I don't have a super secret enemies list. I'm not a Bond villain. I'm just a regular guy, with a regular enemies list.

Sheldon: Point of inquiry. Given that Leonard is your secondary friend and Koothrappali is your primary friend, why didn't you seek refuge under his roof?
Howard: There's no room. His sister is staying with him.
Leonard: Wait, wait. What?
Sheldon: Cocoa, Leonard. Focus. I'm down in the dumps here.

Sheldon: Yes, hello. This is Dr. Sheldon Cooper. Yeah, I'm at 2311 North Robles Avenue. Yeah, I'd like to report a dangerous wild animal. A blue jay. I'm sorry, this is Animal Control. I don't understand the laughter. No, the bird is not in my home. If he was in my home, I obviously would have called 911. Sir, I have no doubt that there are things that you're frightened of. Being stuck in a dead-end public service job? Or your wife stepping out on you because you're stuck in a dead-end public service job? Or spiders? Don't you think I tried making cat noises?
