Leonard: This is cool. When was the last time you and I built something together?
Howard: Scientifically? A little over a year ago. LEGOs? Last week in my room.
Leonard: If there was a Nobel Prize for Millennium Falcons that fall apart when you pick them up, we'd be set.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Leonard: Penny, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. You know maybe I don't need to understand it, I just need to be grateful. I love you, Penny.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Amy: I got here as quickly as I could.
Sheldon: You're too late.
*Sheldon plays "Taps" and drapes a cloth over his laptop."
Amy: Sheldon, this is silly.
Sheldon: You got emotional when that lab monkey died.
Amy: That lab monkey told me he loved me in sign language.

Sheldon: You look amazing. I mean, this resolution is remarkable.
Amy: (On Skype) I really had to go home for this?
Sheldon: Yes, but it's like you're right here in the room.
Amy: And yet, I'm not.
Sheldon: But I feel like I could reach out and touch you.
Amy: And yet, you can't.
Sheldon: I know.

Amy: Well, the guy at the store said this one is great.
Sheldon: Oh. Oh, the guy. Oh, pardon me. I didn't realize you'd spoken to the guy. Yeah, tell me, did the guy choose one with a 4K display and a Thunderbolt port?
Amy: Yes.
Sheldon: Yeah? Did the guy make sure that this has a one terabyte solid-state drive?
Amy: Yes.
Sheldon: Yeah? Oh, well, was this guy Rick from Computer Solutions on Colorado?
Amy: Yes.
Sheldon: Yeah, well, he does know his stuff.
