Wolowitz: Oh, more details about the new Star Trek film. There's going to be a scene depicting Spock's birth.
Raj: I'd be more interested in a scene depicting Spock's conception.
Sheldon: Oh, please. For Vulcans, mating—or if you will, pon farr—it's an extremely private matter.
Leonard: Still, I'd like to know the details. His mother was human; his father was Vulcan. They couldn't just conceive.
Wolowitz: Maybe they had to go to a clinic. Can you imagine Spock's dad in a little room with a copy of Pointy Ears and Shapely Rears?

Sheldon: Teams are traditionally named after fierce creatures, thus intimidating one's opponent.
Raj: Then we could be the Bengal Tigers.
Sheldon: Poor choice—gram for gram, no animal exceeds the relative fighting strength of the army ant.
Raj: Maybe so, but you can't incinerate a Bengal tiger with a magnifying glass

Raj: Too bad, I called dibs.
Wolowitz: You can't just call dibs.
Raj: I can, and I did. Look up "dibs" in Wikipedia.
Sheldon: Dibs does not apply in a bidding war

Leonard: Come on, guys, push!
Howard: If I push any harder I'm gonna give birth to my colon.
Raj: I can't feel my fingers. Hurry up!
Sheldon: It's the same amount of work no matter how fast you go—basic physics.
Raj: Sheldon, if my fingers ever work again, I've got a job for the middle one

Wolowitz: Okay, you two have to back off.
Raj: Why should I back off? You back off, dude.
Leonard: Excuse me, this is my apartment, and she's my roommate's sister.
Howard: So what? You've already got Penny.
Leonard: How do I have Penny? In what universe do I have Penny?
Wolowitz: So, I can have Penny?
Leonard: Hell, no!

Raj: Missy, do you enjoy pajamas?
Missy: I guess.
Raj: We Indians invented them. You're welcome.
Wolowitz: Yeah, well, my people invented circumcision

Raj: Hey, look, I found an iPod!
Wolowitz: Smashed beyond repair—what are you going to do with it?
Raj: What else? Sell it on ebay as "slightly used"

Leonard: [Sheldon] says he's moving out.
Raj: What did you do? Did you change the contrast or brightness settings on the television?
Leonard: No.
Raj: Did you take a Band-Aid off in front of him?
Leonard: No.
Wolowitz: Did you buy generic ketchup? Forget to rinse the sink? Talk to him through the bathroom door?

Raj [to Leonard]: What about Leslie Winkle?
Sheldon: Oh, no.
Raj: Why?
Sheldon: Her research methodology is sloppy, she's unjustifiably arrogant about loop quantum gravity, and to make matters worse, she's often mean to me

Raj: Did you see my limo downstairs?
Leonard: Yeah.
Raj: It's bigger than the house my grandfather grew up in.
Leonard: Great.
Raj: It has more food, too

Rajesh: Isn't there a University policy against dating graduate students?
Leonard: No. If you can talk to them, you can ask them out.
Rajesh: Damn, there's always a catch

Sheldon [to Kripke]: Also, I am given to understand that your mother is overweight.
Raj: Oh, snap.
Sheldon: Now of course, if that is the result of a glandular condition and not sloth and gluttony then I withdraw that comment.
