Sheldon: But you don't have a life-threatening condition. Why would you take the risk of surgery?
Leonard: Sheldon, it's a routine procedure.
Penny: I've heard you complain about his snoring.
Sheldon: We... Yes, for the first five or six years, but I've gotten used to it. It helps me sleep. He's like my mucus-powered white noise machine.

Amy: It's not you. Now think, there's a car named after him.
Sheldon: Of course there is. The Mini Cooper, 'cause it's me.
Amy: How about this: he's a poor man's Sheldon Cooper.
Sheldon: Oh, Tesla.

Whoa, whoa, whoa, whoa. Just because I love you doesn't mean girls are allowed in my room.

Amy: Sheldon, there's something else I've been wanting to say, but before I do, I just... I want you to know that you don't have to say it back.I know you're not ready, and I don't want you to say it just because social convention dictates...
Sheldon: I love you, too.
Amy: You said it.
Sheldon: There's no denying I have feelings for you that can't be explained in any other way. I briefly considered that I had a brain parasite. But that seems even more far-fetched. The only conclusion was love.

Amy: Well, you can relax. Just because you think I look pretty doesn't mean we have to spend the night together.
Sheldon: Were you hoping we would because it's prom?
Amy: I'm always hoping. But tonight I just wanted to have a nice time with you. And maybe dance with someone who has arms.

Amy: What's going on?
Sheldon: What's going on is we're about to go to a prom. And there's a great deal of pressure on young couples like us to engage in what Mr. Bob Eubanks called making whoopee.

Leonard: You know, if you're not gonna learn how to do this, they make some pretty good clip-ons.
Sheldon: Bruce Wayne doesn't wear a clip-on. Bruce Wayne doesn't make his roommate tie it for him.
Leonard: His name is Alfred, and, yes, he does.

Penny: Here's a question-- as an alien pretending to be human, are you planning to engage in any post-prom mating rituals with Amy?
Sheldon: There are post-prom mating rituals?
Penny: Not always. Unless your date drives a van with an air mattress, then always.
Sheldon: Well, if it's part of the prom experience, then I'm open to it.
Penny: You're kidding.
Sheldon: I may be an alien, but I have urges.If Amy wants to copulate by firing her eggs into space, well, then, I will happily catch them with the reproductive sac on my upper flermin. I'm not the best at reading facial cues, but I can see that you're a little turned on.

Sheldon: Hold on, Doctor. Leonard, where are your social skills?This man is clearly upset. We should invite him in for a hot beverage.
Leonard: He tried to score with Penny.
Sheldon: So have these two, and they're having dinner with us.

Raj: I was trying to help you! And at the first sign of trouble you ran away, leaving me to fend off a family of rats! You're a completely selfish human being and a... and a physical and a moral coward!
Sheldon: His statements of the obvious continue to annoy.

Raj: So, as Hannah Montana, Miley was a world-famous pop star.But then she would take off her wig and go to school like a normal girl. Which, I don't have to tell you, at that age, is its own headache.
Sheldon: That's preposterous. How would she go unrecognized
just by wearing a wig?
Raj: But you're okay with Superman concealing his identity with a pair of glasses?
Sheldon: He doesn't just put on a pair of glasses. He combs back his curlicue and affects a mild-mannered personality.

Raj: It's also a live mine, so there'll be dynamite explosions going off in the distance.
Sheldon: Yeah, I have a lactose-intolerant roommate with a taste
for ice cream. Next.
Raj: Oh, you have to be down there for 12 hours at a time.
Sheldon: Yeah? We have to be somewhere.
Raj: Well, there's no toilets-- we'll have to do our business
in a bucket.
Sheldon: So it's settled-- we're not doing it.

Oh, Bernadette, please play my clarinet.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.
Penny: That's... rum and Coke without the rum.
Sheldon: Yes, and would you make it diet?
