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.

Raj: Hey, Penny. Happy Star Wars day!
Penny: Okay.

Raj: Can I make you breakfast? Admiral Ackbar's Snack Bar is open for business!

Penny: Thank you for being the emotional one in this relationship.
Leonard: I got your back

Penny: You know Klingon.
Leonard: That's true.
Penny: No, I meant that as a regret.

Sheldon: I thought that subject had run its course, so I changed it. It's called reading the room, Amy.

Sheldon: Quite all right. After my forehead melanoma scare, I've learned not to sweat the small stuff.
