Sheldon: I was going to make you a red zinger, but since Mars is the red planet I went for peppermint.

Amy: And who says you could even survive an inter-planetary mission anyway? You could barely survive a tiny turtle bite.
Sheldon: First of all, this has only made me stronger.

Sheldon: So you're saying you wouldn't leave me for the chance to be one of the first humans to colonize another planet?
Amy: I would at least mention it before filling out the application.
Sheldon: Hmm. That's exactly what Leonard, Wolowitz, Koothrappali, Bernadette and Penny said.

Penny: Now come on, we are gonna do this.
Leonard: Yeah. You get the paint, I'll rest for thirty to forty minutes, and then we do this.

Penny: Come on, we are not old, boring people. We can do better than this.
Leonard: That's true. How late did we stay up last night?
Penny: Almost 1 am.
Leonard: Damn straight almost 1 am. And we weren't even watching TV, we were watching Netflix like the kids do.
Penny: Yeah. Is it a comedy, is it a drama? Nobody knows!

Penny: Did we move at all?
Leonard: Maybe a long the Z axis, but X & Y are looking pretty sad.

Sheldon: This again. Amy, I've already had one new hole torn in my body today, I don't need another one.

Sheldon: I can't believe you almost had me bring a wild animal into my home.
Amy: No one told you to poke the turtle's face.
Sheldon: I was playing "Got your nose". That's how you get children to like you.

Raj: Oh no, oh no, oh God, no.
Howard: You know what? You sound busy. I'm going to let you go.

Raj: What are you doing?
Howard: Just playing video games while Bernie does the taxes.
Raj: What are you a little kid? Is she gonna cut your dinner in to little pieces, too?
Howard: She doesn't have to. I filled up on Jelly Beans.

Howard: How are the taxes going?
Bernadette: Okay, but you've got a lot of receipts for the Lego store in here.
Howard: Those are business expenses. You can write those off.
Bernadette: A $200 R2-D2 is a business expense?
Howard: Oh, Bernie, you're gonna have to sound a lot more confident when we get audited.

Bernadette: What's happening?
Howard: Raj was snooping through Emily's drawers and broke one.
Bernadette: Oh, I'm gonna miss her.

Penny: So, what do you think?
Leonard: I thought it would be a little more ... just more.
Penny: I'm not even sure why we were out of breath.

Sheldon: What should we name him? I came in thinking Seth, but he kinda looks Italian.

Leonard: I got you something for Valentine's Day and I was too embarrassed to give it to you.
Penny: Why?
Leonard: Because I got it at the dirty store.
Penny: You went to the dirty store without me?
Leonard: In sun glasses and a hat after I parked two blocks away.
