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 body density. If I run too deep a bath, I drown.

Sheldon: Oh, ow, blueberry in my nose, blueberry in my nose!
Leonard: Snort it down and keep eating!

Leonard: Well, I'm done with Penny. I'm going to be more realistic and go after someone my own speed.
Raj: Like who?
Leonard: I don't know. Olivia Geiger?
Sheldon: The dietitian at the cafeteria with the limp and the lazy eye?
Leonard: Yeah.
Sheldon: Well, I don't think you have a shot there.

Leonard: How do I look?
Sheldon: Could you be more specific?
Leonard: Can you tell I'm perspiring a little?
Sheldon: No. The dark crescent-shaped patterns under your arms conceal it nicely.

Amy: You know, I could use an engineer on this project.
Sheldon: Well, now, this works out great. Howard's an engineer. I'm sure he knows someone qualified.

Leonard: So Howard and Amy working together, that's interesting, huh?
Sheldon: Eh, it's all right, I suppose. Uh, when- Usually when Amy complains about her coworkers, I just tune her out, but now I'll be able to join in and pound away.

Amy: Hi.
Sheldon: Welcome home. How was work?
Amy: Great. Howard had an idea for-
Sheldon: (waving his hand dismissively) That's enough about work.

Sheldon: This whole thing is maddening.
Bernadette: I'm really busy. I don't have time to listen to you complain.
Sheldon: Hey! You're complaining, too. "Sheldon, why are you here?" "Sheldon, the applesauce is for the baby."

Sheldon: Wait, wait, now, hold on. Why'd you ask me about Tom Sawyer?
Bernadette: I'm just interested in you.
Sheldon: Well, you are sweeter than your applesauce.

Raj: Guys, you won't believe this. I stopped by the university to check in on Howard and Amy, and they were having fun.
Sheldon: Well, don't worry. He won't be having any fun when he gets home. I did all his favorite chores!

Amy: Sheldon, when I said couples costume, I meant like Romeo and Juliet or Cinderella and Prince Charming, not two robots from some silly movie I don't even like.
Sheldon: Okay, I'm gonna let that slide because I know you're hopped up on tea bags.

Amy: How about Raggedy Ann and Andy? I loved them growing up.
Sheldon: No, I don't think so. Those dolls represent three things I do not care for: clowns, children and raggedness. I think it's a lost cause.

Amy: Hang on, I have a question. Do you have any experiments that aren't life-threatening?
Sheldon: Come on! That was a perfect take, and you ruined it. Oh, look! Hey, I did need enraged.

Raj: Hey guys, guess who I found at LAX. My baby sister Priya.
Sheldon: Excuse me. I object. You propose a guessing game, yet you don't give me enough time to guess. For the record, I was going to say your sister Priya.

Leonard: So, Priya, what brings you back to LA?
Priya: I have a one day layover on my way to Toronto. Corporate merger.
Raj: Can you believe it? Little Priya's one of the lead attorneys for the biggest car company in India.
Sheldon: Given that when we met her she was finishing law school and planning an internship at a large Indian car company, it's actually extremely plausible.
Leonard: And your poll numbers just keep dropping.
