Raj: You just have to wait for science to catch up or technology to get cheaper. Think about, uh, DVD players. They used to cost, like, a thousand dollars, but just the other day I used one to smash a bug.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

Raj: Okay, here we go. [to Leonard & Penny] Say cheese. [to Sheldon & Amy] Say cheese. [to Howard & Bernadette] Say cousin.

Sheldon: Wow! You look beautiful.
Amy: Really? 'Cause I was gonna return it.
Sheldon: Why would you return it? You look like a pile of swans.

Penny: What if you asked for $20 million?
Sheldon: I'm sorry, I'm trying to do science, not hire Lady Gaga to come to my birthday.
Penny: Do you even know who Lady Gaga is?
Sheldon: Presumably, the wife of Lord Gaga.

Sheldon: So with this level of high-power laser array, we would actually be able to solve the black hole information paradox once and for all.
President Siebert: That's impressive, and how much funding were you looking for?
Sheldon: $20 million.
President Siebert: Really? You think you can build that for $20 million?
Sheldon: Not a chance.
President Siebert: I'm sorry, then why are you asking me for it?
Sheldon: Because once you've spent $20 million, you're much more likely to give me an additional 50.
President Siebert: So actually, what you're saying is with $70 million, you can build this.
Sheldon: I can see why you'd think that, but no. You can't go to the board of trustees and say you gave Sheldon Cooper $70 million and have nothing to show for it. No, the only way you'd be able to save face is to double down.
President Siebert: So 140?
Sheldon: And then double again.
President Siebert: 280?
Sheldon: And then - good news - not quite double again. So, uh, what do you say? We have a deal?
