Leonard: Penny, I think I know what to do. Sheldon, I have some more bad news.
Sheldon: More?
Leonard: I'm afraid so. You know the cashew chicken I get you Monday nights?
Sheldon: Yes. From Szechuan Palace.
Leonard: Szechuan Palace closed two years ago.
Sheldon: What? Where did my cashew chicken come from?
Leonard: Golden Dragon.
Sheldon: No. No, this isn't right. Our food always comes in Szechuan Palace containers.
Leonard: Yeah, well, before they went out of business, I bought 4,000 containers. I keep them in the trunk of my car.

Sheldon: Now, Penny, we don't consume alcohol during Dungeons and Dragons. It impairs our judgment.
Penny: Oh, this isn't alcohol. It's a magic potion that makes me like you.
Leonard: Double potion, please.

Leonard: Wait, I got it. I got it.
Bernadette: Congratulations. You got it last.
Leonard: You're really mean, you know that?

Howard: Have you tried rebooting him?
Leonard: No, I think it's a firmware problem.

Leonard: I know shopping cheers you up, but it's not really my thing.
Penny: Well, how about this helicopter you control with an iPad?
Leonard: Does it have a camera in it?
Penny: It does have a camera in it.
Leonard: Baby's listening.

Leonard: He always needs all the attention. He's such a baby.
Penny: I know. I know.
Leonard: I swear he is never playing with my helicopter.

Sheldon: Uh-oh. According to this Mexican Customs Web site, visitors may not bring more than five laser discs, 20 compact discs or 12 VHS tapes.
Raj: We don't have any of those.
Sheldon: How can you be sure? VHS was king when Feynman drove this van. For all we know, there are hidden compartments lousy with Jane Fonda workout videos.
Leonard: If there was a hidden compartment, don't you think you'd be stuffed in it by now?

Wil Wheaton: See, that's what I mean. When you wake up in the morning, whether this is the greatest movie ever or a total piece of crap, your life isn't going to change at all.
Howard: He's right.
Leonard: Yeah. No matter what happens, we're coming back tomorrow to watch it again.

Leonard: Sheldon, we've been together so long, it's hard to remember a time you weren't in my life. And believe me, I try.
You make me laugh.
You make me a better scientist.
You make me crazy.
You're more than just my roommate, you're my brother.
Sheldon: Thank you.
Leonard: Happy birthday, buddy.

Sheldon: We have seven people and two cars. In the lead car, driven by Leonard, will be myself, Amy Farrah Fowler and Penny.
Amy: Yes! He had you in the other car, but I got you upgraded.
Penny: Yay.
Sheldon: She made the case that if we break down in the middle of nowhere, your Nebraska backwoods skills and brawny hands will give us the best chance to survive in the wild.
Penny: Brawny?
Leonard: They're bigger than mine.

Sheldon: I don't understand why I can't talk at this meeting.
Leonard: 'Cause when you talk, it enrages people.

Howard: Why would the military want Sheldon?
Leonard: I don't know. Target practice?

Sheldon: Are you having an allergic reaction to my boutonniere?
Leonard: No. I'm just so happy for you. And for me. After today, you are officially - and, more important, legally - Amy's problem.
Sheldon: Don't be silly, Leonard. I will always be your problem.

Leonard: I have something that might help. It's-it's a recording of the only person whose opinion Sheldon actually respects.
Amy: Hawking? Feynman?
Leonard: No, himself.

Leonard: It's a pep talk he made when he was a kid. He gave it to me years ago and told me to save it for a real emergency.
Penny: What? You didn't break it out when he declared his room a sovereign nation and waged a trade war against us?
Leonard: His major export is talking. I didn't want that anyway.
