Raj: This morning, I fired my dog walker.
Howard: Oh. How's the dog gonna go to the bathroom?
Raj: Uh, I gave her an Imodium. That's tomorrow's problem.

Leonard: I even said "off the chain mail," and she still wants to go.
Sheldon: That's probably my fault. She may have heard about my cool Dumbledore costume.

Leonard: Anyway, I figured I can hang out with my friends and have fun too.
Bernadette: Well if your idea of fun is riding in a minivan to Target for diapers, things are about to get nuts.

Sheldon: Amy is studying the time lag between intent and awareness, and I realized that applies to the measurement problem in quantum mechanics. Now, I recognize there will be a time lag between me saying that and you Googling what it means, so I'll wait.
Leonard: I understand it, Sheldon.
Raj: Yeah, me, too.
Howard: I'm sorry, I spaced. Are we still talking about the spoon?

Leonard: We're pinned down!
Howard: We can't get through!
Raj: Sheldon, get over here and help!
Sheldon: Okay, one second.
Leonard: Sheldon, why are you jumping up and down?
Sheldon: I'm trying to shoot.
Howard: Then use the shoot button, not the "wonderful thing about Tiggers" button!

Penny: Okay, Beverly, aren't you overreacting a little? All we know is they shared a cab and had a nightcap.
Sheldon: And turned their phones off.
Leonard: Not helping, buddy!

Bernadette: It didn't help that you couldn't walk a straight line when the cop pulled you over.
Howard: I have performance anxiety. You of all people should know that.

Susan: Well, fine, if everyone wants to make jokes about our problems, then I can, too. Knock, knock.
Who's there? Our family is an embarrassment.
Randall: That's not much of a joke.

Sheldon: Hang on, hang on! We're smart, we can figure this out. Okay, so: Mary and Beverly can't be together. Uh, Alfred and Beverly can't be together. Leonard and I can't be together. Now, I could be with Alfred but I don't like his face.

Susan: Oh, Leonard! It's so nice to see you again!
Leonard: Oh, you, too! Hey, everyone, this is my mother, Beverly.
Beverly: Hello.
Susan: Hi.
Randall: We are not white trash!

Amy: Are you excited to see your son walk down the aisle?
Alfred Hofstadter: Yes, I am. I'm just feeling a little guilty about all the trouble I've caused.
Mary Cooper: Oh, so am I.
Sheldon: You made God sad today, Mom.

Howard: Why wouldn't that colonel say what the meeting's about? It has to be bad news.
Raj: Calm down, okay? Try not to think about it.
Howard: That's really stupid advice.
Raj: You know that hurts my feelings.
Howard: Calm down, try not to think about it.
Raj: (upbeat) Okay.

Leonard: Can I get anyone a drink?
Wyatt: Well, I could use another beer.
Susan: (loudly) You're done! (softly) He's done.

Marty: Hello.
Howard: Hey, Marty. Thanks for talking to us.
Marty: Hey, no problem. Thanks for going to outer space so no matter what I do my mom will be disappointed in me.
Howard: Well, I married a little Catholic girl, so we're even.

Bernadette: I've worked so hard to get where I am, and I don't want to get sent back to square one because I'm pregnant.
Amy: I understand how you feel.
Bernadette: Thank you.
Amy: I wish there were some way I could make it better.
Bernadette: Well, you brought me French fries. That's a start.
Amy: Uh, actually, I got you apple slices 'cause you're pregnant.
