Raj: Why does Emily like this stuff? Do you think there's something psychologically wrong with her?
Howard: What difference does it make?
Raj: What do you mean?
Howard: Come on, she could have a freezer full of ex-boyfriends' body parts and you'd still go out with her.
Raj: I do like that the ex-boyfriend's out of the picture.

Bernadette: I have to go. Penny ratted me out. FYI, she's getting you a watch for your birthday with money she took out of your wallet.

Sheldon: What can we do that's fun?
Leonard: What can we do that's different?
Penny: What can we do that's free?

Leonard: Hey, how about we bring back Anything Can Happen Thursdays?
Penny: That's good. Why'd you guys stop doing that?
Leonard: You made fun of us. Said it was stupid.
Penny: Yeah, sounds like me.

Sheldon: Got it! There's a live action role playing group that meets every Thursday night in Griffith park, and re-enacts battles from Lord of the Rings.
Penny: Okay, tell me more about this calzone idea.

Leonard: You know what, why don't we just ease into this? Let's go for a walk and see if we find a new restaurant.
Sheldon: Any chance this restaurant is near Griffith Park? *Brings out a Lord of the Rings - Gandalf hat*
Leonard: No.

Raj: You're a good son. I don't know how you do it.
Howard: Beach blankets, my friend. It's all about beach blankets.

Leonard: Thankfully, Penny and I have a relationship built around honesty.
*Amy and Bernadette chuckle*
Leonard: What? I don't lie to her.
Bernadette: Oh, we know you don't lie to her.

Penny: Since you're paying for dinner, I'll let that slide.
Sheldon: Have you ever paid for a meal?
Penny: Not with money.

Penny: Read.
Sheldon: *Reading fortune cookie* "Your warm and fun-loving nature delights those around you."
Penny: Nope, try again.

Psychic: Does she have dark hair?
Penny: Yes, yes. Your spirit guides are on fire!
Sheldon: The majority of people have dark hair. Even you at one time.

Psychic: Does she work in a similar field to you?
Sheldon: Hah, the opposite. I'm a physicist and she's a neurobiologist. My spirit guides can go suck an egg.

Psychic: He should give himself to this relationship. Once he does, all his other pursuits will come into focus.
Penny: Sheldon, you hear that? Amy is the key to your happiness.
Psychic: Exactly. Personally and professionally. Everything will fall into place once you commit to her.

Raj: Here we go. Night of a Thousand Corpses.
Emily: Just so you know, I was a nanny for three years, so if you get scared I can totally change your diaper.

Sheldon: My mother would lock her car if she had to drive through his hodgepodge of ethnicity.
