Leonard: Hey, what's going on with your hair?
Raj: Uh, nothing. I just decided to stop straightening it.
Penny: Wait, so you were making your hair look like that on purpose?
Raj: When I first moved to America, I wanted to fit in. And Howard's hair was straight, and he was the coolest person I knew.
Penny: Then you never saw any other people?

Sheldon: So this is for Amy's birthday. Can I leave it here?
Leonard: Sure. What is it?
Sheldon: A butter churn.
Penny: Aw, that's what I got her.

Leonard: Uh, hurry. Raj is on next.
Penny: All right. I can't believe they canceled Vampire Diaries but they'll show this.
Leonard: This is the news.
Penny: And that was a woman torn between two hunky vampires. What is your point?

Penny: So, I guess the only thing that actually stays the same is that things are always changing.
Sheldon: Interesting. So you're saying the inevitability of change might be a universal constant.
Penny: Well, there's a little more to it than that, but, yeah, sure.

Leonard: Was Amy suspicious when they had to let your dress out?
Penny: No. She was so happy, she didn't even question it.
Leonard: Someone's gonna figure it out. Why don't we just tell people?
Penny: No, it's too early. I haven't even wrapped my head around it.
Leonard: I have. My head is wrapped.
Penny: Yeah, well if something else had been wrapped, we wouldn't be in this situation.

Amy: What happened to "I'm never gonna have kids"?
Penny: It was an accident. I went out drinking with Sheldon.
Amy: [gasps] Oh, my gosh. We're sister wives?
Penny: No! Then I went home and slept with Leonard.
Amy: While fantasizing about-
Penny: Leonard. And a little Idris Elba.

Penny: You mean like a beta test?
Leonard: Well, technically, this would be an alpha test. A beta test requires people that weren't involved in the development of the appli-
Penny: Seriously, do I not get credit for knowing beta test?
Leonard: No, absolutely you should.

Penny: Oh, damn, they canceled my Visa. Oh, yay, a new MasterCard.

Penny: All right, time to open bachelor number two.

Penny: Oh man, did the KISS Army repeal "Don't Ask, Don't Tell"?

Penny: You know, I believe in ghosts, too.
Leonard: Great.
Penny: And astrology.
Leonard: I know, and pyramid power and healing crystals.
Penny: Oh, no, no, no, crystals don’t work.
Leonard: Really, that’s the line? Psychics are real, but crystals are voodoo?
Penny: Oh, Voodoo is real. You don't want to mess with Voodoo.

Penny: Yo, Raj, talk to me. I'm sorry, just screwing with you.

Penny: Hey, jerk face, you forgot your iPod.

Penny: Not even the one on the breast feeding crisis?
Leonard: It was not a crisis. Apparently I favored the left one, she got a little lopsided.
Penny: Oh my God, you still go left!

Leonard: Besides, can you even name one romantic thing you've done for me?
Penny: I can name tons.
Leonard: And sex doesn't count.
Penny: Oh.
