Sheldon: Let's take this problem one step at a time. First, we need to decide whether we're calling it lee-ver or lev-er.
And the sooner we decide it's lee-ver, the sooner we can roll up our slee-ves - and not sle-ves - and get to work.
Leonard: We're going to be here for ee-ver.

Penny: Why am I so nervous?
Bernadette: It's understandable. Amy was afraid to tell her mom she broke up with Sheldon.
Penny: Yeah? How did it go? Did she make you crawl into the breaking-up drawer?

Amy: Uh, well, actually, to be honest I haven't told her yet.
Penny: You've been giving me a hard time and you haven't even told your mom about Sheldon?
Amy: I'm feeling a little dizzy from all the blood loss. I don't know what you're talking about.

Howard: What are you doing?
Raj: It's called Lamaze breathing. It helps you push.
Howard: Great! He's pushing with his uterus.

Bernadette: Amy, I noticed your status still says "in a relationship" on Facebook.
Amy: You're right. I should probably let all of my Facebook friends know.
Penny, I'm no longer in a relationship.

Amy: How long do you think you can keep it from him?
Bernadette: Yeah, isn't it gonna get worse the longer you wait?
Penny: Well, not necessarily. You know, Dad's not getting any younger, so if I wait long enough, I'll just tell him he walked me down the aisle and it was magical.

Raj: When did you learn how to change a tire?
Howard: Every self-respecting gentleman should know how in case he comes across a damsel in distress by the side of the road.
Sheldon: If I see one scorpion, I am getting on someone's shoulders and never coming down.
Leonard: And there's your damsel.

Penny: There you go, you're all done!
Amy: That wasn't so bad. Nice!
Boy, if my mom could see me now, she'd lock me in the sin closet.
Bernadette: That's a joke, right?
Amy: Actually, the joke was on her. I could still see the TV through the slats.
Penny: I'm starting to see why you and your mom aren't very close.

Sheldon: Leonard?
Leonard: What?
Sheldon: I am getting too old for this crud.

Sheldon: What was that?
Howard: I think it's a tire.
Sheldon: What if it's banditos shooting at us? What if we get kidnapped? What if we end up in a factory making Bart Simpson pinatas for the rest of our lives?

Amy: Piercing my ears.
Penny: Oh.
Bernadette: Oh, you really never had that done?
Amy: My mom said pierced ears were for whores, pirates and genies.
Penny: Okay, well, you're a grown woman now.
Amy: I know, but Sheldon had this clause in the Relationship Agreement forbidding cosmetic surgery unless it's to look like a Klingon.

Bernadette: We'll take you to the mall to get it done.
Penny: Why? I can do it right here.
Amy: Really? You have a piercing gun?
Penny: No. All you need is a needle and an ice cube. I've done it, like, a dozen times.
Amy: Oh, I don't know.
Penny: Oh, come on. I'll be gentle. Let me take your ear virginity.
Bernadette: This party's weird.

Leonard: Hey, watch your speed. I hear the Mexican police target tourists.
Howard: Oh, not a problem. If anything goes down, we just put Koothrappali in the driver's seat and slap a sombrero on his head.
Raj: Dude, how many races can you offend in a single breath?
Howard: I don't know. Have you watched the Olympics with me?

Leonard: Sheldon, can you believe that we're driving in a van that was owned by one of the greatest scientific minds of the 20th century?
It's like the Batmobile. If Batman was real and a physicist and his car wasn't cool.

Raj: Perhaps some of his mojo will rub off on us. Maybe between this and his beach house, we will be inspired to greatness.
Sheldon: I usually don't put too much stock in charms and talismans. However, even I must admit feeling Richard Feynman's butt dent cupping my own bottom that does get the creative juices flowing.
Howard: Hey, I have to return this van. Keep your creative juices in your pants.
