Penny: Hey, guys.
Leonard: Hey. What are you doing here?
Bernadette: We heard there were some sexy scientists working hard all weekend.
Penny: Yup, so we brought you some lunch and we are gonna go look for 'em.

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: Soup, sandwiches and emasculation, just like my mom used to make.

Penny: So, hows it goin'?
Leonard: Good. Slow.
Howard: There's a lot of tedious setup, but once we get through that it should go quicker.
Penny: Is there anything we can do to help?
Leonard: You know what, this part isn't that technical. You actually could.
Penny: Wow, really? Called my bluff. All righty then.

Bernadette: Can we really help?
Howard: While we finish soldering these boards, it'd be great if you guys could wrap these pipe fittings with Teflon tape.
Leonard: I'll show you how to do one.
Penny: Hey, wouldn't it be funny if after all your years of hard work, I'm the one who makes a scientific breakthrough? (To Bernadette) He doesn't think that's funny.

Amy: Sheldon, why don't you get a new computer? You know that one's out-of-date.
Sheldon: Oh, but I like this computer.
Amy: The video is failing, and the sound is cutting out.
Sheldon: I'm sorry, I didn't get that.
Amy: The video is failing, and the sound is cutting out.
Sheldon: I'm sorry, one more time. The sound is cutting out. (Amy holds up a sign) I can't read that. The video is failing.
Amy: Get a new computer.
Sheldon: What?
Amy: Get a new computer.
Sheldon: What? (Answering phone) Hello?
Amy: Get a new computer!

Amy: I didn't understand your e-mail.
Sheldon: Uh, can you repeat that? You're breaking up.
Amy: I didn't understand your e-mail.
Sheldon: Ah. Yeah, I had to get a little creative because the S, R and M keys on my laptop stopped working.
Amy: Deaw Aby, could you pleathe dwive be to the twain thtow thubtibe tobowow?
Sheldon: So, is that a yes?

Penny: Wait, wait, wait. What are these changes on page six?
Amy: Sheldon, what did you do?
Howard: I should've known.
Bernadette: "25% of profits due to Sheldon Cooper will be allocated to a scholarship fund for the firstborn child of Howard and Bernadette Wolowitz." Sheldon, that's so nice.
Leonard: That beats the onesie I was gonna get them from Baby Gap.

Howard: That's very generous, Sheldon.
Sheldon: Oh, I've always valued education over money. And the very fact that you needed a written guarantee of respect made me realize how dismissive I've been of your contributions.
Howard: I appreciate that.
Sheldon: And I just hope that this scholarship can rescue your child from the sub-par education and menial life of an engineer.
Amy: Sheldon!
Sheldon: What? I didn't sign it yet.

Sheldon: The revisions I made start on page four.
Penny: Wow. That is a lot of "whereupons".
Amy: You should see the Valentine's Day card he gave me.

Howard: "Article three: As it pertains to this project, Dr. Sheldon Cooper promises to abstain from all insulting or disrespectful language directed toward Howard Wolowitz, including but not limited to: mockery of engineering, his height, his hair, his wardrobe, and his insane belief that the Ghost Rider movie was, quote, 'not that bad'."

Leonard: Hang on. Maybe there should be a "no insult" clause about me, too.
Sheldon: Do you still like cilantro?
Leonard: Yeah.
Sheldon: You're tying my hands here.

Leonard: Howard, what do you think?
Howard: I'm on board.
Sheldon: I'll add it right now. Oh, baby, it's addendum time!

Leonard: They've been out there a while.
Amy: I hope everything's okay.
Sheldon: I wonder what they're talking about.
Penny: (eavesdropping at the door) If you guys would shut up, I could tell you.

Howard: But, um, we were talking, and I'm a little concerned about the three of us forming a partnership.
Sheldon: Are you suggesting a limited liability corporation? Cause I did not L-L-"see" that coming.
