Penny: Sheldon, what do you want?
Sheldon: I want soup.
Penny: Why didn't you just ... Why didn't you just have soup at home?
Sheldon: Penny, I have an IQ of 187. Don't you imagine that if there were a way for me to have had soup at home I would have thought of it?
Penny: You can have soup delivered.
Sheldon: I did not think of that.

Penny: Okay, what kind of soup do you want?
Sheldon: Well, my mother used to make me this split pea with little frankfurter slices and these home made croûtons.
Penny: We have Chicken Tortilla and Potato Leek.
Sheldon: Can I get any of those with little frankfurter slices and home made croûtons?
Penny: No.
Sheldon: Then surprise me.

Penny: Sheldon, you are a grown man, haven't you ever been sick before?
Sheldon: Well, of course, but, not by myself.
Penny: Really, never?
Sheldon: Well, once. When I was fifteen, and spending the summer at the Heidelberg Institute in Germany.
Penny: Studying abroad?
Sheldon: No, visiting professor. Anyway, the local cuisine was a little more sausage-based than I'm used to, and the result was an internal blitzkrieg with my lower intestine playing the part of Czechoslovakia.

Penny: And there was no-one there to take care of you?
Sheldon: No. No, my mum had to fly back to Texas to help my dad because the house had slipped off the cinder blocks again.
Penny: Again?
Sheldon: It was tornado season. And it was an aluminum house.

Sheldon: Wait. Will you please rub this on my chest.
Penny: Oh, Sheldon, can't you do that yourself?
Sheldon: Vaporub makes my hands smell funny.
Penny: But Sheldon-
Sheldon: Please, please, please, please, please, please, please.
Penny: I can't believe I'm doing this.
Sheldon: No, no, counter-clockwise or my chest hair mats.

Sheldon: Do you think Penny will come here and take care of us?
Leonard: I don't think Penny’s ever coming here again.
Sheldon: I'm very congested.
Leonard: Yeah, so?
Sheldon: Can you go to the kitchen, and get me the turkey baster labeled mucus.
Leonard: If I stand, I'll vomit.
Sheldon: Under the sink, yellow Tupperware bowl.

Sheldon: Can you sing Soft Kitty?
Penny: What?
Sheldon: My mom used to sing it to me when I was sick.
Penny: I'm sorry, honey, I don't know it.
Sheldon: I'll teach you. [sings] "Soft kitty, warm kitty, little ball of fur, happy kitty, sleepy kitty, purr purr purr." Now you.
Penny: [sighs] [sings] Soft kitty, warm kitty…
Sheldon: Little ball of fur. Keep rubbing.
Penny: Little ball of fur.

Sheldon: (Knocking on Penny's door early in the morning). Penny, Penny, Penny!
(Penny opens the door).
Sheldon: Good morning.
Penny: Do you have any idea what time it is?
Sheldon: Of course I do. My watch is linked to the atomic clock in Boulder, Colorado. It's accurate to one-tenth of a second, but as I'm saying this it occurs to me once again your question may have been rhetorical.

Leonard: How long is he going to stay here?
Sheldon: He's a homeless drug addict, Leonard. Where's he going to go? Boy, you have a lot to learn about lying.

Sheldon: I am uncomfortable having been included in your lie to Penny.
Leonard: What was I supposed to say?
Sheldon: You could have told her the truth.
Leonard: I could not have said that, it would have hurt her feelings.
Sheldon: Is that a relevant factor?
Leonard: Yes.
Sheldon: Then I suppose you could have agreed to go.
Leonard: What would I have said afterwards?
Sheldon: I would suggest something along the lines of "singing is neither an appropriate vocation nor avocation for you and if you disagree, I recommend you do a CAT scan to locate the tumor which is pressing on the cognitive processing center of your brain".

Penny singing "Out Tonight"
Leonard: What the hell is that?
Sheldon: I don't know, but if cats could sing ... they'd hate it too.

Penny: You'll never guess what just happened.
Leonard: Oh, I give up.
Sheldon: I don't guess. As a scientist, I reach conclusions based on observations and experimentation. Although it occurs to me, you may have been employing a rhetorical device rendering my response moot.

Sheldon: Leonard?
Leonard: Yes?
Sheldon: (Sarcastic) When we played chess earlier, you were terrific, and I can't wait to play you again. Goodnight!

Sheldon: If she were to log on to www.socalphysicsgroup.org/activities/other, click on upcoming events, scroll down to seminars, download the PDF schedule, and look for the seminar on molecular positroneum, well then, bippity boppity boo, our pants are metaphorically on fire.
*Leonard shuts the door.*
Sheldon: Well, sir, my trousers will not be igniting today.

Toby: Damn you, Chaplain Horrigan.
Penny: I'm sorry?
Toby: The Phillipines: 1992: The Subic Bay Naval Station: A young boy on the cusp of manhood. His only companions, mongrel dogs and malarial mosquitoes. Desperate and alone, he reached out to a man who promised to introduce him to a merciful, loving God. But instead introduced him to a gin-pickled tongue shoved down his adolescent throat. What choice did he have but to drink, shoot, and snort his pain away?
Sheldon: Don't forget genetic predisposition towards addiction.
Toby: That's never been proven.
Sheldon: There have been studies.
Toby: Not double-blind studies!
Sheldon: How could there be double-blind study? Who would be the control group?
