Leonard: I'd suggest using some lubricant, but I have a feeling you fell on that as well.
Howard: Not funny, Leonard.
Raj: Really? A robot hand’s got a death grip on your junk, dude. That’s funny, ask anyone.

Howard's mom: Howard, I made cookies for you and your little friends.
Howard: That's great, mom. Thanks.
Howard's mom: I'll bring them up with some Hawaiian Punch.
Howard: *startled* Don't come up here!
Howard's mom: Why not? Are you ashamed of your mother?
Howard: Yes, but that's not the point. Get me out of here!
Leonard: Do you have any ideas, Raj?
Raj: Right now all I can think about is cookies and Hawaiian Punch.

Raj: The Good Wife is on. I tell you, this is my new Grey's Anatomy.

Raj: I'm telling you, dude. The only way to feel better about Penny going out with other guys is for you to get back on the whores.

Raj: Go away. She wants New Delhi, not Kosher deli.

Howard: What the hell are you doing?
Raj: Relax, it's Nyquil.
Leonard: You still have a cold?
Raj: Maybe, but I don't care. That's the great thing about Nyquil, it's like ten-percent booze. I call it the nighttime sniffling, sneezing, coughing, so you can talk to girls medicine.

Raj: Hey, Leonard?
Leonard: Yeah?
Raj: I haven't had sex in a year.
Leonard: Where are you going with this, Raj?
Raj: Don't flatter yourself, dude.

Leonard: I'm not going out tonight, Raj.
Raj: All right. Would you mind if I went to your room and downloaded some Asian pornography?
Leonard: Very much.
Raj: Doesn't have to be Asian.

Raj: Look at this. Do you think she's really doing that or is it PhotoShop?
Leonard: I'm pretty sure Martha Stewart never got naked with a room full of big, fat Japense guys.
Raj: You don't know that. Prison changes people.

Leonard: What about you, Raj?
Raj: Oh, there it is. Now that you don't have a girlfriend, you want to hang out with me again.
Leonard: I never stopped hanging out with you.
Raj: Oh, please, we all know I'm the friend you call when you have no other options. If we were the Justice League, I'd be Aquaman.

Leonard: Don't worry. You'll meet a girl someday.
Raj: No, I won't.
Leonard: Yes, you will, and she'll be beautiful, and kind and sexy and funny and everything you ever wanted in a woman.
Raj: You really think so?
Leonard: I do, and you'll fall hopelessly in love and give her your heart. And she'll take it and grind it into pathetic, little pieces.
Raj: But we'll have sex first, right?

Sheldon: I got lost.
Leonard: How could you get lost? Your phone has GPS.
Sheldon: Satellites are down. Solar flares.
Raj: There are no solar flares right now.
Sheldon: Yes, there are.
Raj: Dude, I'm an astrophysicist. If there were solar flares, I'd be all up in it.

Raj: Hey, do you think the elastic woman in The Incredibles needs to use birth control or can she just be a diaphragm?
Howard: Well, that's it. We're officially out of things to talk about.

Raj: Ah beer, the magic elixir that can turn this poor shy Indian boy in the life of the party ... Oh yeah!

Wolowitz: Okay, forget giant ants. How about giant rabbits?
Raj: Big or small, I don't like rabbits. They always look like they're about to say something, but they never do.
