Raj: I'm so lucky I take after you.
Dr. Koothrappali: You think you take after me?
Raj: Well, I try to. I certainly wouldn't be a scientist if you hadn't been my role model.
*to Sheldon, Howard and Bernadette after talking to his dad*
Who wants to go to Vegas in a real helicopter?!

Raj: Hello, Daddy.
Dr. Koothrappali: What did you say to your mother?
Raj: Nothing. I was just calling to check in, make sure she's doing okay.
Dr. Koothrappali: Well, after talking to you, she seems to think I'm some sort of playboy.
Raj: Really? I don't know where she'd get an idea like that.

Bernadette: Ready to call tech support?
Howard: Give me the number. Probably wind up talking to some foreign guy who's reading from the same manual I have.
*Raj's phone rings. Sheldon, Howard, and Bernadette stare at him in shock*
Raj: It's my father, you jerks.

Howard: All right. All systems go. In five...
Boys: ...four, three, two, one.
*An electrical crackle is heard and smoke comes out of the drone*
Sheldon: That's what my train used to do.

Howard: All right, the power supply is reconnected. I think we're back in business. Let's just run a few tests before we take it outside. Sheldon, we got WiFi?
Sheldon: Check.
Howard: GPS?
Raj: Check.
Howard: Battery charged?
Sheldon: Check.
Bernadette: Four hours of our lives gone? Check.

Penny: Oh, hello. Hi. I didn't know he was going to point it at me, so don't do drugs and stay in school.
Leonard: They're graduating.
Penny: Okay, bye!

Bernadette: I call tech support all the time.
Howard: You call tech support!
Sheldon: Ha-ha!
Raj: What a baby!

Bernadette: Why don't you just call tech support?
Sheldon: Hey!
Howard: Whoa!
Raj: Not cool!
Bernadette: What?
Howard: There's two kinds of people in this world. Those who call tech support and those who make fun of the people who call tech support.

Raj: You guys don't have to go to the trouble. I'm back in the money now. I can just buy another helicopter.
Howard: It's not about the money. It's about solving a problem. It's why I became an engineer. It's what I like to do, it's what I'm trained to do. It's who I am.
Sheldon: Oh, look at you, the little engineer that could.

Sheldon: Sorry. Ah, maybe it's for the best. I hear locomotive smoke is the second leading cause of death among train aficionados.
Raj: What's the first one?
Howard: Suicide.
Sheldon: Wrong. Obesity.

Penny: You're gonna be on Skype. They're not gonna see your legs.
Leonard: Well, I'm gonna go put on some pants just in case. But, I have to say, this is very freeing.
Penny: Add a belt and I'll take you some place nice.

Penny: Sweetie, you know you're supposed to wear clothes under a graduation gown?
Leonard: A. Surprised you know that. B. I wanted to look like a sexy graduate for you.

Mrs. Koothrappali: Well, however much money your father was giving you, I'll give you more.
Raj: Thank you, Mummy! I love you! *to Sheldon and Howard* Helicopters for everybody!

Mrs. Koothrappali: Rajesh, is your father seeing someone?
Raj: All I know, Mummy, is that he's a single wealthy doctor, and now, for some reason, there's no money for your little boy.

Raj: Anyway, speaking of Daddy. I had a very strange conversation with him. He said he couldn't afford to send me money any more because of his active social life.
Mrs. Koothrappali: What does that mean, "active social life"?
Raj: Well, let's not talk about him or whatever shenanigans he may or may not be up to. Let's talk about you.
