Raj: Whoa. Humongous man crush, dude.

Howard: Yep. It's officially a bro-mance.

Dave: I don't know how you live next door to that without doing something about it.
Leonard: Actually, science is my lady.

Sheldon: What it is is a cacophonous assault of eucalyptus, bayberry, cinnamon and vanilla. It's as if my head were trapped in the pajamas of a sultan.

Leonard: I've been offering to show you around for a year and a half. You always said you had yoga.
Penny: I never said that.
Leonard: Maybe I heard you wrong. A lot of words sound like yoga.

Leonard: Oh, a gift certificate for motorcycle lessons. Very thoughtful.
Penny: Yeah, and I checked. Not letting the bike fall on you while standing still is lesson one.

Leonard: Oh, then I think you'll appreciate what I got you.
Penny: Okay. 101 Totally Cool Science Experiments for Kids.
Leonard: You know, 'cause you're so into science.

Barry Kripke: Well, if you have any delusions about entering him against my robot, the Kripke Crippler, in the Southern California Robot Fighting League Round Robin Invitational - AKA the SCRFLRRI - his name is going to be Scrap Metal.

(O.S. - In video) Barry Kripke: As you can see, the Kripke Crippler is reducing the Chevy Cavalier to rubble.

Leonard: Nice little bot you've got here.
Barry Kripke: I'm aware.
Leonard: What's this do? Spin?
Barry Kripke: Yeah, at 3400 RPM. It can cut through steel like it was rubber.

Barry Kripke: What is his problem?

Sheldon: Never. I'd rather see MONTE dead than in your hands.
Barry Kripke: That can easily be arranged.

Sheldon: Your robot is inferior and it will be defeated by ours because ours exceeds yours in both design and execution. Also, I'm given to understand that your mother is overweight.


Raj: Oh, snap.


Sheldon: Now of course if that is a result of a glandular condition and not sloth and gluttony, I withdraw that comment.


Raj: What difference does it make, fat is fat.


Sheldon: There are boundaries!

Barry Kripke: Nope, I wanna climb some rocks.

Barry Kripke: Come on, they have birthday parties here. Little kids climb this.
