Sheldon: Wow, I don't know which hurts more. My nose or my heart.

Sheldon: He were go, compromising again. We really are the best.

Sheldon: Amy, there was a song I couldn't get out of my head. Eventually, I realized the song was about you, and like that earworm, I can't get you out of my heart. So, what I'm trying to say is, you're my heartworm. The metaphorical kind, not the poodle-killing kind.

Sheldon: What can I do for you ladies?
Amy: You have something we want.
Sheldon: Oh, dear. My mother warned me this is what happens to pretty boys in the big city.
Penny: No, we just want information.
Sheldon: Oh. I've got that spades. Ravage me.

Leonard: It's 3 in the morning!
Sheldon: 3 in the morning is a good time for bongos.
Leonard: I was sleeping!
Sheldon: Leonard sleep while I play bongos.
Leonard: No, I don't.
Sheldon: Leonard no sleep while I play bongos.

Sheldon: (In Mandarin) Show me your mucus. Your mucus!
Chen: (Mandarin) Blow your own nose and go away!
Sheldon: (Mandarin) This is not a tangerine bicycle. Show me your mucus!
Chen: Crazy man. Call the police.
Sheldon: (Mandarin) No, don't call the library. Show me your mucus.

Leonard: That is not a compromise. A compromise is me driving you everywhere because you refuse to learn how.
Sheldon: Oh, I learned how. Amy taught me.
Leonard: What?! Then why don't you do it?
Sheldon: Well, it's scary, and sometimes I get the pedals mixed up. But more importantly, driving me to work is one of the things that gives your life purpose. I can't take that away from you, so what do I do? Come on, I'm practically feeding you the answer. I compromise.

Amy: It's actually steamier than it looks. Sheldon's looking up the phallic symbolism of root vegetables in renaissance paintings.
Sheldon: Oh no, I got bored of that. I'm just browsing cuticle scissors on Amazon.

Penny: This has gotten way out of hand, okay. I've done some stupid things, you've done some stupid things. How about we just call it even, and move on with our lives?
Sheldon: I've done no stupid things.
Penny: Look, you've gotta meet me halfway here.
Sheldon: I am meeting you halfway. I'm willing to concede that you've done some stupid things.

Sheldon: Sorry, kid, you got it worse than a gibbon.

Leonard: It's nice that you called them esteemed.
Sheldon: You're right, I'll take that out.

Leonard: I'm bleeding!
Sheldon: Like a gladiator.

Sheldon: You set it on DTS, didn't you?
Leonard: I had to, she called me cutie.

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 Marshall to determine.

Penny: Normally, I can just ignore you. I mean, I get it. You're a little peculiar. Like Sheldon.
Sheldon: Excuse me, Penny, but in this room, you're the one who's peculiar.
