Sheldon: Amy, the relationship agreement was not designed for either one of us to get our way.
Amy: You use it to get your way.
Sheldon: I use it to get the right way. The fact that the right way is also my way is a happy coincidence.

Penny: Sheldon, she wanted to show you off to her family, and you stood her up, okay? Look at this adorable, smushy face. Smush, smush, smush, smush.
Amy: You're hurting me.
Penny: No, Sheldon hurt you.
Amy: Before; now it's you.
Penny: Oh.

Raj: Here you go. I've got everything well need for the big game. Low fat turkey jerky, low-carb beer, 100-calorie snack packs.
Leonard: You pick up a Y chromosome while you were there? You might be short one.

Sheldon: I always thought if I were enslaved, it would be by an advanced species from another planet. Not some hotsie-totsie from Glendale.

Leonard: Raj, Imperial Troopers on your tail.
Raj: Got him. When Gandhi advocated his philosophy of non-violence, I bet he didn't know how much fun it was killing stuff.

Mrs. Wolowitz Howard Joel Wolowitz, I've been worried sick for two days and I know you turned off your phone. You open this door right now because I've had it up to here! I have been to the morgue and the hospital, and I spent the last half hour walking up these fakakta stairs.

Leonard: All right, I think we got them all. Let's divide up the loot.
Bernadette: Ooh, look at this pretty purple robe I just got. You should put on yours and then we'll match.
Howard: But I worked hard to get this Armour.
Bernadette: Sorry, I just thought it'd be nice if people knew we were a couple.
Howard: Fine, I'll change.
Sheldon: (whip sound app) Ha-ha.

Sheldon: Hello, Penny. I just stopped by to bring you this gift.
Penny: Gummy bears? Thank you.
Sheldon: Now that you're in my debt, please manipulate Amy into releasing me from my commitment to attend her aunt's tedious birthday party.

Bernadette: Get that guy! Get that guy! Pew! Pew! Pew! Pew!
Sheldon: Dr. Rostenkowski, it may interest you to know that saying pew, pew, pew isn't as effective as pressing your blaster key. In the same way that saying whee doesn't make the land speeder go.
Bernadette: (aiming at Sheldon) Pew!

Sheldon: What else?
Stuart: Hmm. Oh, have this collectors edition Batman utility belt. Maybe she can use it as a wearable pill caddy.
Sheldon: Well, she'd just look silly wearing that without the rest of the costume.

Raj: Bernadette, remember, your character's the healer in our group. You're in charge of healing all of us, not just Howard.
Bernadette: I can't help it. My Howie Wowie has an owie.

Sheldon: No, Leonard, go ahead and mock. Like my daddy always said, Shelly, women aren't anything but flippin pains in the bottom.
Leonard: That's what your father used to say?
Sheldon: Well, I took out the bad words and the yeehaw, but you get the gist.

Penny: Where are you going?
Sheldon: Wherever the music takes me, kitten.

Sheldon: I feel like a teen heartthrob.

Leonard: It's 3 in the morning!
Sheldon: 3 in the morning is a good time for bongos.
Leonard: I was sleeping!
Sheldon: Leonard sleep while I play bongos.
Leonard: No, I don't.
Sheldon: Leonard no sleep while I play bongos.
