Penny: Okay, the reason he deceived you is you were being
a pain in the ass.
Sheldon: The reason I was being a pain in the B is because I was worried about him, and no one else was.
Penny: Really? You won't even say "A"?
Sheldon: You bet your sweet B I won't.

Sheldon: I assume this medical center's already treated the burns on your bottom from the recent pants fire.
Penny: 'Cause I'm a liar, liar?
Sheldon: That's for the fire marshal to determine.

Leonard: If there was an asteroid strike,wouldn't you die, too?
Sheldon: I don't know-- I'm smart and scrappy, I think I'd find a way.

Leonard: Buddy, I-I get that you're worried about me and I-I appreciate that, but I'm not going to die.
Sheldon: You don't know that.
Leonard: Well... I do know that it won't be from an asteroid strike.
Sheldon: You know who else said that? Every cocky T. Rex currently swimming around in the gas tank of your car.

Sheldon: If the surgery is successful, the snoring is gone. And if you die during surgery...the snoring is gone.
Leonard: It sounds like either way, I finally get some rest.

Sheldon: I'm listening to you snore. I'm wondering how I'll ever sleep without it.
Leonard: If it helps you sleep, then why are you sitting here
staring at me like the albino boogeyman?
Sheldon: Really, Leonard-- insults? After I spent two hours in your closet waiting for you to fall asleep?

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.

Sheldon

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.
