Sheldon: We did it! What? I said we.

Sheldon: If we're all through playing "Mock the Flawed Technology", can we get on with Halo Night? We were supposed to start at 8, it is now 8:06.

Leonard: You have a TV in your room. Why don't you have breakfast in bed?
Sheldon: Because I am neither an invalid nor a woman celebrating Mother's Day.

Sheldon: I've been sitting in garbage!

Sheldon: I need my wrist brace. All this button pushing is aggravating my old Nintendo injury.

Penny: Oh, please, it's not a time machine, if anything, it looks like something Elton John would drive through the Everglades.
Sheldon: It only moves in time, it would be worse than useless in a swamp.

Sheldon: Oh, no, not Morlocks, not flesh eating Morlocks! Help!

Missy: (Talking to the guys) He was trying to build some sort of armed robot to keep me out of his room.
Sheldon: Made necessary by her insistence on going into my room.

Sheldon: Waitresses don't yell at you at Big Boy.

Sheldon: Another carnal fiasco with the shiksi goddess.
Howard: Shiksa. Shiksa.
Sheldon: Forgive me, Yiddish was not spoken in East Texas, and if it was, it wasn't spoken for long.

Sheldon: In the words of Khan Noonien Singh in the immortal Wrath of Khan: "He tasks me, he tasks me and I shall have him."
Raj: No doubt! Sign here.
Sheldon: (Signing) "From hell's heart, I stab at thee."

Penny: So, how was paint ball? Did you have fun?
Sheldon: If you consider being fragged by your own troops fun. (To Howard) You clear a space on your calendar. There will be an inquiry.

Sheldon: Leonard, it's two in the morning.
Leonard: So?
Sheldon: So, it's my turn.

Sheldon: Just because your career's been stagnant for a few years, that's no reason to give up.

Penny: That's amazing.
Sheldon: I wouldn't say amazing. At best it's a modest leap forward from the basic technology that gave us Country Bear Jamboree.
Howard: Hey, Sheldon? Ahem.
Sheldon: Yes?
*Howard commands the robot arm to perform a hand gesture*
Sheldon: Peace?
Howard: No, not peace. Hang on.
