Alex: Here's your frozen yogurt, Dr. Cooper.
Leonard: This should be fun.
Sheldon: Half chocolate, half vanilla, side by side, not swirled?
Alex: Yes.
Sheldon: Half a teaspoon of sprinkles?
Alex: Rainbow, not chocolate.
Sheldon: Two cherries?
Alex: One on top, one on the bottom.
Sheldon: Stems removed?
Alex: Um, top one, yes. I didn't check the one on the bottom.
Leonard: Oh!
Alex: I'm so sorry, Dr. Cooper.
Sheldon: It's all right, Alex. I'm not mad at you, I'm just disappointed.

Alex: It's okay, I've been around scientists all my life. My dad's an astronomer at SETI.
Leonard: Oh, SETI, the Search for Extraterrestrial Intelligence. You should introduce him to Sheldon. The search is over.

Alex: So, what kind of research are you doing?
Leonard: High-energy lasers.
Alex: Ooh. Military?
Leonard: Not yet, but I can remove unwanted hair from two miles away.

Amy: You were right. I had nothing to worry about. That skank's your problem, not mine.

Amy: Look at you, putting on a brave face.
Penny: There's nothing to be brave about. Everything's fine.
Amy: Really? I don't know how much you know about primate behavior, but Sheldon's assistant was clearly courting Leonard. Were she a mandrill, she would have bent over and displayed her brightly colored hindquarters like a big red welcome mat. By the way, you try that at the junior prom, you get kicked out.

Penny: So, how was work today?
Leonard: Ah, it was all right, I guess. Got to Heimlich a cherry stem out of Sheldon. Caught Raj right in the eye.
Penny: Oh, you're kidding.
Leonard: No, Raj had to go to the nurse.
Penny: Wow. Anything else?
Leonard: Mmm, the nurse is a woman, so he couldn't talk to her. She had to bring him a Grover puppet so he could point at what hurt.
Penny: Oh, is that it?
Leonard: Isn't that enough? It had the weaponized fruit and a puppet. What more do you want?

Alex: Sheldon thinks the approach in this paper might change the way we calculate ferromagnetic hysteresis.
Penny: Oh, it's about time. I hated the old way.

Leonard: Where are we going?
Penny: My limbic system wants to take your pants off.

Bernadette: Come on, let's go home so I can tear off those little pants.
Howard: Great. Just keep in mind astronauts lose a lot of muscle tone in space, so you might have to do most of the heavy lifting.

Howard: Well, that was quick and a little gross. Now I know how she feels.

Penny: Hey, Sheldon, you're always full of fun little facts. Where did the expression get your ass handed to you come from?
Sheldon: Don't know.
Penny: I wonder if it's from like ancient Rome where they'd actually chop somebody's ass off and then go, here. You know, to appease Loseroneous, the God of losers.

Amy: Why don't we do something athletic like go over to the university pool and play water polo?
Leonard: No good, Sheldon doesn't float.
Sheldon: That is true. I have a higher than normal bone density. If I run too deep a bath, I drown.

Sheldon: Wait, I'm a little concerned. Blueberries are rich in antioxidants.
Leonard: So?
Sheldon: So, with all those antioxidants, what if I run out of oxidants?

Raj: Okay, the NASA Web site says Howard's final descent has begun.
Sheldon: He left a boy, he returns a boy-sized hero.

Howard: (singing) Baruch atah, Adonai, Eloheinu. Melech haolam, hamotzi. Lechem min haaretz
Mike: What's that?
Howard: The Jewish prayer for eating bread. We don't have one for falling out of space!
