Sheldon: It's an earthquake. I knew it.
Penny: Sheldon, it's just a little tremor.
Sheldon: A little tremor that turns routine sinus surgery into a frontal lobotomy.

Howard: I really don't like how your wings poke me when we sleep because you're an angel.

Howard: I love that I'm a slob around here and you're kinda okay with that.
Bernadette: Uh-huh. And I love that I work and do all the cleaning and you're okay with that.

Raj: How can I be okay? I come from a broken home!

Sheldon: You're acting odd. Why?
Amy: I'm odd all the time. Everyone knows that. Just last night, I tried to see how many Fava beans I could fit in my mouth.
Sheldon: Tell me the truth.
Amy: 28.
Sheldon: Come on.
Amy: 56.

Amy: It's sweet that you care about him so much.
Sheldon: I do. And I wouldn't be able to forgive myself if something happened to him, and I wasn't at his bedside to say "I told you so".

Sheldon: Why would you have surgery?
Leonard: Because I can't breathe. I snore. I get sinus infections.
Penny: Back off, he's all mine.

Sheldon: I've learned that 1 in 700,000 people die from general anesthesia.
Leonard: But do you realize that means 699,999 people don't die?
Sheldon: I suppose that's true. You're such a glass half full kind of guy. I'm going to miss that.

Leonard: Buddy, I get that you're worried about me and I appreciate that, but I'm not going to die.
Sheldon: You don't know that.
Leonard: 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.

Amy: This is an easy one. You love this guy.
Sheldon: Me.
Amy: Come on. He's an under appreciated genius.
Sheldon: Still think it's me.
Amy: It's not you. Now think, there's a car named after him.
Sheldon: Of course there is. The Mini Cooper because it's me.
Amy: How about this? He's a poor man's Sheldon Cooper.
Sheldon: Oh, Tesla.

Bernadette: Howard, get off of him.
Howard: Not until he stops humping his way up my family tree.

Sheldon: I really did think you looked pretty.
Amy: You did?
Sheldon: Yes. So much so that I started to panic.
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. Maybe dance with someone who has arms.

Sheldon: Thank you for understanding.
Amy: Of course I understand. Sheldon, there's something else I've been wanting to say, but before I do, I just. I want you to know 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 that 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.

Sheldon: Wow, wow, wow, wow. Just because I love you, doesn't mean girls are allowed in my room.
