Wolowitz: Sheldon. You remember the first few weeks; we were looking for magnetic monopoles and not finding anything, and you were acting like an obnoxious, giant dictator?
Raj: I thought we were going to be gentle with him.
Wolowitz: That's why I added the "tator"

Wolowitz [after seeing Penny jump Leonard]: Damnit, I should have gone over and said we were back
Raj: Yeah, it was "first come, first serve."

Wolowitx: You think you can put up with Sheldon?
Raj: Well I'm a hindu. My religion teaches that if we suffer in this life, we're rewarded in the next. Three months in the north pole with Sheldon and I'm reborn as a well hung billionaire with wings

Wolowitz: Just imagine ... if he says yes, we'll have an entire summer without Sheldon.
Raj: We could play outside.
Wolowitz: We could sit on the left side of the couch.
Leonard: I could use the bathroom at 8:20!
Raj: Our dreams are very small, aren't they?

Wolowitz: This is the thing from the pizza box that keeps the lid from touching the cheese.
Raj: Is that what this is for? In India, the lid just touches the cheese. Of course, we also have rampant poverty and periodic outbreaks of chlorea so a little cardboard on our cheese is no biggie

Sheldon: Why does Leonard get to go?
Wolowitz: Because he's upset over his situation with Penny, and if I have to hear about it again, I'm gonna kick him in his ovaries

Leonard: Hey, how's it going?
Wolowitz: Cut the crap, you set this up, didn't you?
Leonard: Yes..
Wolowitz: She's a hooker, isn't she?
Raj: A prostitute, yes
Wolowitz: You already gave her the money?
Leonard: Yes
Wolowitz: ... Thank you

I'm a horny engineer, Leonard. I never joke about math or sex

In bars, all across this great nation of ours, Thursday night is Ladies Night. Which means that as the evening progresses, we will get better looking courtesy of 99 cent margaritas and 2-for-1 Jello shots

Wolowitz: First we let the lawyers and the jock thin the heard, then we go after the weak, the old and the lame
Leonard: That's your system?
Wolowitz: Yeah and if you spot a girl with a seeing eye dog, she's mine

Wolowitz: Okay! Let me just go inside and slip off my underwear.
Leonard: Why?
Wolowitz: Well if I get lucky, I certainly don't want to be caught in my Aquaman briefs.

Raj: The Wolowitz coefficient?
Wolowitz: Neediness times dress size squared

TBBT Quotes

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.

How is "doable" anything but a compliment?
