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.

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

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.

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.

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

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

Sheldon: During the seven month space flight, I can keep up morale with my wacky sense of humor. Hey, Leonard, is there any peanut brittle left in that can?
Leonard: You mean this weirdly suspicious one?

*Sheldon throws a pie at Leonard*

Leonard: I mean I was on fire. I was in the zone like an athlete.
Penny: Sweetie, I beat you at this, too.

Amy: What I want is for us to be planning our future together.
Sheldon: And in that future, are we on the same planet? Because I've seen people make the long distance thing work.
Amy: We're on the same planet!

Amy: I guess we'll have to make a new video together as a couple.
Sheldon: Good idea. And as you've had such a rough day, I'm gonna let you throw the pie in Leonard's face.

Raj: Thank you for forgiving me.
Emily: It's okay. At some point we were bound to have our first fight.
Raj: Well, it almost happened when you called my Apple Pie crust doughy. But the truth is, you were right and I was just angry at myself.

Leonard: Please go to Mars.

Amy: Let's pick ourselves out a nice turtle. Ooh, how about this one up on the log?
Sheldon: Hmm, I don't know. He kinda looks like a jerk.

Penny: No, come on, I wanna do it. Let's you, me and your very, very pale feet make some art.

Leonard: So, where do you want to hang it?
Penny: Are you kidding? We're not hanging it.
Leonard: But it's an expression of our love.
Penny: And our butts. Not hanging it.
