Barry Kripke: I like to floss before I eat so my gum pockets are open to new food.

Barry Kripke: Hello. How did I walk past you? I'm Barry.
Penny: Penny.
Barry Kripke: That's not a very hot name. I'm gonna call you Roxanne.

Rajesh: Die, Toaster, Die!

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

Howard: Behold the Mobile Omni-Directional Neutralization and Termination Eradicator! Or...
Leonard, Sheldon, Howard, Raj: Monte.

Sheldon: This is an auspicious moment, like Robert Oppenhiemer or Neil Armstrong, we need the appropriate words to mark this historic scientific event.
Rajesh: How about, die toaster, die!
Leonard: That'll do it!

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.

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.

Sheldon: What did the toaster oven ever do to you?
Leonard: What did I do to Jimmy Mullins in the third grade? He still punched me in the face with my own fists. Sorry, you little nerd. You were just in the wrong boys' room at the wrong time.

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: 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!

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

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.

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?
