Howard: Just flip the switch until the lights on the drone change to solid yellow.
Sheldon: All right, that seems simple enough. Initiating calibration sequence. *flips switch rapidly* One, two, three, four, five, six, seven, eight, nine, ten. *lights on drone turn solid yellow* Well, I suppose ten is technically "at least ten." But they're still getting at least one angry letter.

Howard: Step one, rapidly flip the calibration switch from the fully up to the fully down positions for at least ten times.
Sheldon: It actually says "at least"?
Howard: Yeah.
Sheldon: Why would they say "at least"? Is it 10 toggles? Is it 100 toggles? Is it 1,000 toggles? 10,000 toggles? 100,000 toggles?
Howard: Sheldon!
Sheldon: You see where I'm going with this.

Howard: Okay, the WiFi extender is on, the camera's on, they're both on the same network. We should be getting an image.
Sheldon: All I see is a black screen, and my own reflection. I look sad.

Leonard: I worked hard on that speech, too.
Penny: Oh. You could tell it to me.
Leonard: Oh, thank you, but I'm okay.
Penny: Are you sure? I could pretend I'm a high school cheerleader who can't control herself around esteemed alumni.
Leonard: Greetings, distinguished cheerleaders.
Penny: Ooh!

Leonard: Well, I'm excited to show you around.
Penny: You think we'll have time to visit your mom over there?
Leonard: Yes. We'll also have time to put my junk in a garlic press, but I'm not doing that either.

Penny: I've never been to New Jersey before.
Leonard: It gets a bad rap from shows like Jersey Shore and Real Housewives.
Penny: So it's not really like that?
Leonard: No, it's like that.

Leonard: How'd you get ready so fast?
Penny: Oh, I packed light. Once I got through an entire spring break with nothing but a long T-shirt and a belt.
Leonard: Why'd you need a belt?
Penny: It's called an evening look.

Bernadette: Well, now you get to go back as a successful scientist.
Amy: With a beautiful girl on your arm.
Sheldon: And a pointy hat sticking out of your eyeball.

Amy: I think it's really nice that you're sharing this experience with Penny.
Leonard: I thought it'd be fun to show her my old stomping grounds. I even know the exact spot where they used to stomp me.

Raj: The problem with commencement speeches is that they're boring. Ooh, do you own a T-shirt cannon?
Howard: Why would he own a T-shirt cannon?
Raj: I don't know. Why do I own one?

Leonard: I'll take my chances.
Sheldon: Fine. I wonder if they make "I told you so" cards in Braille.

Amy: Leonard, have you ever given a high school commencement speech before?
Leonard: No. It's pretty exciting.
Sheldon: Aren't you afraid of being blinded?
Leonard: How would I be blinded?
Sheldon: At the end of the ceremony, all the students throw those pointed hats in the air. It's all "Pomp and Circumstance" until someone loses an eye.

Sheldon: If your bathroom floor counts as a carry-on, you're packed.

Leonard: Okay, we should leave in about an hour. You all packed?
Penny: Uh, yeah, I just need to throw in a few last-minute things. You know, makeup, underwear, clothes.

Raj: It's like the best one they make, I just can't get it to work.
Howard: I'll figure it out.
Raj: It streams HD videos straight your phone when it's flying.
Howard: Nice. Where were you when I was single?
