Sheldon

What's going on?

Oh, Howard's gonna sleep here tonight. He had a fight with his mother.

Sheldon

Did you offer him a hot beverage?

[long pause] No.

Sheldon

Leonard, social protocol states: when a friend is upset, you offer them a hot beverage such as tea.

Tea does sound nice.

Sheldon

You heard the man, Leonard. [snaps his fingers and gestures to the kitchen]

[Leonard starts to walk to the kitchen]

Sheldon

And while you're at it, I'm upset that we have an unannounced houseguest, so make me cocoa.

Sheldon

Where are you going?

I'm having dinner with Priya at Raj's. I think Howard's gonna be there; you wanna join us?

Sheldon

But tonight's Thursday. On Thursdays, everybody comes over here and has pizza, or a reasonable facsimile prepared by someone claiming to be Luigi, but who sounds suspiciously like Jackie Chan.

Can we make a one time exception for tonight.

Sheldon

We could. We could also stop using the letter M, but I think that idea is isguided and oronic.

Just come with me to Raj's.

Sheldon

I don't want to go to a party.

It's not a party; it's the same group of people who hang out here hanging out over there.

Sheldon

I'm sorry, but 5 people eating and chatting is a party.

How come it's not a party when we do it over here?

Sheldon

Because we don't throw parties.

Sheldon

[frustrated in trying to figure out Howard's magic trick] This deck is rigged in some fashion.

Fine. Get another deck and I'll do the trick with that [one].

Sheldon

So you're saying this is a regulation deck?

[shouting] I'm saying, believe in magic, you Muggle!

S4 E18 The Prestidigitation Approximation
View quote →

[to Howard] Y'know, I think I know how you did the card trick.

Sheldon

Oh, please. If I don't know, you don't know. That's axiomatic.

C'mere. [whispers in Howard's ear]

You're right.

Not too bad for someone who doesn't know what "axiomatic" means.

[Leonard knocks on Todd Zarnecki's front door]

TZTodd Zarnecki

Who is it?

Sheldon

Your doom!

Don't say "Your doom". Who opens the door for their doom?

Sheldon

Good point. [to the door] Basket of puppies.

Sheldon

I must say, Amy, pretending to have intercourse with you has given me a great deal of satisfaction.

Slow down, Sheldon. I'm not quite there yet.

S4 E20 The Herb Garden Germination
View quote →

[Sheldon has joined Penny, Bernadette and Amy Farrah Fowler on their girls night out at a bar]

Sheldon, have you ever kissed a girl?

Sheldon

Other than my mother, my sister and my mee-maw, no. But in the interest of full disclosure, I was once on a bus and had to give mouth-to-mouth to an elderly nun who passed out from heat exhaustion. Every year I get a Christmas card from her, signed with far too many X's and O's.

That doesn't count! Aren't you even a little curious?

Yeah, you're a scientist, where is the curiosity?

I'm available for experimentation [turns towards Sheldon and puckers up]

Sheldon

Thank you, but not necessary. We know everything there is to know about kissing. It requires 34 facial muscles and 112 postural muscles

Oh blah blah blah. Give me some sugar, bestie. [turns to Penny and kisses her, all three girls start giggling]

Sheldon

I'm certainly glad no one said they were curious about Aztec human sacrifice.

S4 E21 The Agreement Dissection
View quote →

Morning, Sheldon.

Sheldon

Oh, good. You're up. I've written a new and improved roommate agreement that benefits me greatly. I'd like you to sign it.

Why would I want to do that?

Sheldon

Excellent question. Do you remember what happened to the alien, played by talented character actor Frank Gorshin, in the Star Trek episode "Let That Be Your Last Battlefield"?

Uh, Captain Kirk activated the self-destruct sequence and threatened to blow up the Enterprise and kill them both unless he gave in?

Sheldon

Affirmative. [Turns to laptop] Computer, this is Dr. Sheldon Cooper. [laptop beeps in response] Activate self-destruct sequence. Code 1-1-A-2-B.

VFVoice from laptop

Self-destruct sequence activated.

[Sheldon turns the laptop toward Leonard and Priya, showing a timer counting down from one minute]

What are you gonna do, Sheldon, blow up the apartment?

Sheldon

That was my first thought, but all my cool stuff is here.

So what happens when it counts down?

Sheldon

Unless Leonard signs the new agreement in the next…[checks timer] 41 seconds, this computer will send an e-mail to your parents in India saying that you're in a secret relationship with the whiter-than-Marshmallow-Fluff Leonard Hofstadter.

[worried] Oh, my God.

What's the big deal?

Trust me, it's a big deal.

They're gonna find out about me eventually, right?

Yeah, of course, just not today.

Sheldon

20 seconds.

Are you ashamed of me?

Of course not.

Then why can't we just tell your parents?

Please don't push this.

Sheldon

He does that all the time, doesn't he? 15.

Okay, fine, Sheldon, you win. Turn it off.

No, he's bluffing.

Sheldon

I never bluff. 10.

It's blackmail!

Sheldon

9.

We give up.

Sheldon

8.

[unhooking the laptop] This is ridiculous.

Sheldon

It's a laptop with a full charge. [to Priya] Honestly, what do you see in him?

Okay, give him what he wants or we're done.

Sheldon

3.

Really?

Sheldon

2.

Okay, I'll sign it!

[Sheldon hits a key and places a pen on the agreement]

VFVoice from laptop

Self-destruct sequence aborted.

Sheldon

[to Priya as he stands up and leaves] You may have gone to Cambridge, but I'm an honorary graduate of Starfleet Academy.

Sheldon

Good news. I finally have a handle on my idea for 3-person chess.

That is good news. Bye. [starts to leave]

Sheldon

Do you know how I solved the balanced center combat-area problem? Five words: transitional quadrilateral to triangular tesselation.

That…that's brilliant.

Sheldon

It's what I do.

S4 E22 The Wildebeest Implementation

Sheldon

I must say, Amy, I was very impressed to see that Bernadette got her PhD.

It's indeed admirable. Although, it is microbiology.

Sheldon

Your doctorate is in neurobiology. I fail to see the distinction.

I'll make it simple for you. I study the brain, the organ responsible for Beethoven's Fifth Symphony. Bernadette studies yeast, the organism responsible for Michelob Lite.

S4 E24 The Roommate Transmogrification
View quote →
Sheldon

[in response to Howard offering to go for Jamba Juice] No. Jamba Juice is for heroes. [pulls down paintball visor] And that's what we're going to be.

What are you doing?

Sheldon

Following in the footsteps of Kirk, Crunch, and Kangaroo. [walks out for hideout and bares himself, with arms wide open] Geology isn't a real science!!

[Sheldon is then shot down in slow-motion by the rival paintball team, and collapses]

DAMN THOSE SONS OF BITCHES!!

[all other members charge out, and shoot down the rival teams]

Sheldon

[getting up] If there's ever a Church of Sheldon, this will be when it started. [gets hit by another paintball] Ow!

S5 E1 The Skank Reflex Analysis
View quote →

[Sheldon and Amy are talking in her apartment]

Sheldon

I was hoping she [Penny] might listen to you about the dangers of owning unhygienic furniture.

For general educational purposes or has she acquired a bar stool dipped in cholera?

Sheldon

Cholera is water-borne, you're mocking me.

Yes, I am.

Sheldon

Penny has dragged a chair in off the street whose unknown provenance jeopardizes the health and welfare of every resident of our building.

Sheldon, just because you have a focus on cleanliness bordering on the psychotic doesn't mean I have to participate.

Sheldon

All right. Name your price.

[thinks] Kiss me where I've never been kissed before.

Sheldon

…You mean like Salt Lake City?

Sheldon

Thank you for letting me stay here while Leonard skypes with his girlfriend.

Oh, it's no problem. It's actually kind of funny: You reading, me reading, we're like an old married couple.

Sheldon

If we were an old, married couple the wife would serve iced tea and snicker-doodles.

I don't have iced tea and snicker-doodles.

Sheldon

A good wife would go to the store.

I want a divorce.

Sheldon

Good, on your way to see the lawyer pick some tea and cookies.

[sarcastically, to Sheldon] You sound like you had a great night.

Sheldon

I did. How was yours?

Not bad. I had a lot more fun with Amy than I thought I would.

Sheldon

[confused] What exactly do you mean by that?

Well, turns out she really knows how to help a guy loosen up and have a good time…Although, truth be told, my groin is a little worse for wear.

[Short pause, and then Sheldon hits Leonard with his model train]

OW! Why'd you do that!?

Sheldon

To send you a message. She is not for you.

What!?

Sheldon

Not for you!

S5 E3 The Pulled Groin Extrapolation
View quote →

[The group is discussing Raj's new girlfriend possibly taking advantage of him]

Sheldon

I actually have information about Raj that would be helpful with this discussion. [resumes eating]

[long pause] Could you tell us?

Sheldon

Let's see…[rolls dice] Snake eyes. Sorry, bud.

[points to dice] Wait, hang on. Doubles. Roll again.

[Sheldon does so]

Sheldon

…Okay, get this. [Penny and Leonard exchange looks of annoyance] It doesn't matter if he's showering her with gifts. Because the Koothrappalis are vastly wealthy.

What do you mean "vastly wealthy"?

Sheldon

Well, wealthy means a lot of money, and vastly means even more…I'm not sure what's tripping you up.

Oh, I know they have money. I don't think it's that much.

Sheldon

No, you're wrong. See, as you know, a few years ago, I achieved one of my lesser dreams and became a Notary Public. From time to time, I notarized banking documents for Raj. The Koothrappalis aren't just rich. They are Richie Rich rich.

Well, so how much is that?

Sheldon

About halfway between Bruce Wayne and Scrooge McDuck. ($18.5 billion)

[The others look shocked]

[outraged] What the hell! The last time we went to the zoo, that son of a bitch made me buy him a churro!

Listen guys I don't meant to be rude, but I need to go call Raj's sister, who I love so much. So vastly much.
