Barry Kripke: We're all pathetic and creepy, and can't get girls. That's why we fight robots.

Mrs. Wolowitz: Want me to get you a popsicle?
Howard: Cherry, please!
Mrs. Wolowitz: I ate the cherry. All that's left is green.
Howard: You make me wanna kill myself!

Mrs. Wolowitz Howard, there's a blonde girl, Patsy, here to see you.
Howard: Who?
Mrs. Wolowitz Okay, now she's saying it's Penny.

Wolowitz: The way I see it, I'm halfway to pity sex.

Wolowitz: As delicious as the appetizer may be, sooner or later we will have to succumb and eat the entree while its still ... hot.

Penny: Normally, I can just ignore you. I mean, I get it. You're a little peculiar. Like Sheldon.
Sheldon: Excuse me, Penny, but in this room, you're the one who's peculiar.

Mrs. Wolowitz Should I ask Leonard to bring over your homework?
Howard: I don't have homework. I'm a grown man with a master's degree in engineering.
Mrs. Wolowitz Excuse me, Mr. Fancy Pants. Want me to get you a popsicle?

Raj: I'm curious, what part of America is that accent from?

Raj: Okay, what shall be the first to taste the wrath of MONTE?
Leonard: Maybe we should start small.
Raj: Okay, oh, perhaps today is the day we finally find out what's inside the Magic 8 Ball.
Sheldon: Did it when I was 4. It's an icosahedral die floating in tinted blue water.
Raj: Man, call spoiler alert before you say things like that.

Leonard: Remember the day we first met and you asked me to go to your boyfriend's apartment to get your TV back? And he was 9 feet tall and he took my pants off and you said- What was that? What did you say? Oh, yes, you said you owed me one.
Penny: Oh, come on, that's not fair.
Leonard: I came home with no pants.

Penny: What?
Leonard: He said we should maybe enter you in the killer robot competition.

Rajesh: Die, Toaster, Die!

Leonard: Okay, don't take this as a criticism but you do have that over exposed to gamma radiation thing going on.
Penny: What?
Leonard: Usually your the easy going Bruce Banner but when you get angry you turn into (makes growling noise).
Penny: I turn into a bear?
Leonard: Gamma radiation, Bruce Banner; you didn't get the Incredible Hulk from that?

Sheldon: Is it wrong to say I love our killer robot?
Rajesh: As with my father I both love and fear it.

Barry Kripke: Tell you what. Forget the SCRFLRRI, let's settle this roboto-a-roboto. There's no guarantee we're going to go against each other in the round robin, so let's throw down. You know, unless you're afraid.
