Penny: You know, I could totally rock a hat like that.
Sheldon Cooper: That's the work of noted Hollywood costume designer Deborah Nadoolman. She also designed the iconic red and black jacket in Michael Jackson's "Thriller" video, which I've never watched in its entirety, as I find zombies dancing in choreographed synchronicity implausible. And also, it's really scary.
Evil Wil Wheaton: Hey, look who's here! Hey, buddies!
Sheldon Cooper: Well, if it isn't Wil Wheaton, the Jar-Jar Binks of the "Star Trek" universe.
Evil Wil Wheaton: [imitating Jar-Jar Binks] Mee-sa think that very funny!
Sheldon Cooper: Trouble is my middle name, Leonard. Actually, it's Lee, but I prefer Trouble.
Amy Farrah Fowler: The internet suggests that slumber party guests often engage in harmless experimentation with lesbianism.
Bernadette: Where exactly on the internet have you been looking?
Howard Wolowitz: Are you sure you don't want to come with us to "Raiders"?
Bernadette: Oh, no. That movie has melting faces. It reminds me too much of the time I dropped that vial of flesh-eating bacteria into the Rhesus monkey lab.
Penny: You know, Amy, when we say girl talk, it doesn't just have to be about our lady parts.
Amy Farrah Fowler: Shame. Because I have a real zinger about my tilted uterus.
Sheldon Cooper: This is nothing but a blatant abuse of power by a petty functionary. Explain to me why Wil Wheaton and his lackeys get in and we don't!
Joey: Because I'm the petty functionary with a clipboard, bitch.
[Sheldon is upset that Wil Wheaton has been invited to circumvent the line into a showing of the remastered "Raiders of the Lost Ark"]
Sheldon Cooper: This is "Indiana Jones", not "Star Trek". There should be no value to his pseudo-celebrity here.
[shouting at a departing Wil Wheaton]
Sheldon Cooper: And even at Star Trek conventions, they only let him in if he helps set up!
Amy Farrah Fowler: [to Bernadette] What is the circumference of your areolas?
Penny: How does an archeology professor get that good with a whip?
Howard Wolowitz: Maybe he took a class at the adult bookstore. That's how I learned.
Penny: I think I'll pass, but you guys enjoy your extra 21 seconds.
Leonard Hofstadter: I bet if I could make you understand why this is such a cool thing, we'd still be together.
Penny: Hmm... yeah, no we wouldn't.
[Raj whispers something to Howard]
Howard Wolowitz: Uh-huh. I'm guessing 21 seconds had something to do with that, too.
Amy Farrah Fowler: Oh good, a slumber party! We'll do makeovers, initiate phony phone calls, and have spirited pillow fights in our frilly nighties!
