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.

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

Sheldon: Please, I have ideas all day long. Reverse SeaWorld where dolphins are allowed to pet people.
A new clothing size between medium and large called Marge.
Snow White retold from the point of view of Sneezy. Why won't Doc prescribe him something? We finally find out.

Sheldon: It's like when Stan Lee and Steve Ditko invented Spider-man. Stan Lee may get all the credit, but Steve Ditko knows he was just as important. Even though Stan Lee gets to be in all the Marvel movies, and he's far richer, and he's a household name. You know, where as if you say Ditko, that sounds like a company that makes Dits.

Howard: Stuart, we're here.
Raj: It's nice of you to let him keep staying at your mom's house.
Howard: Yeah. Well, I tried putting him out on the curb, but nobody took him.

Leonard: That's not helpful.
Sheldon: Well, I'd give more examples, but everyone in your position is so forgettable.

Howard: It's all defrosting.
Bernadette: It's okay, it's just food.
Howard: It's not just food. This is the last food my mother ever made. This is her last brisket. This is her last meatloaf. This is her last - I have no idea what this is. But, it's the last one.

Leonard: That's not necessary.
Sheldon: It is. They're what hold back the urine and faeces.

Sheldon: Leonard, have you ever noticed only my name is on the cable bill?
Leonard: Yeah.
Sheldon: Good, good. And your name is on the electric bill, and mine isn't. And I'm okay with that.
Leonard: Actually, your name is on the electric bill.
Sheldon: Right. This is a disaster.
Leonard: I don't even know what you're talking about and I agree.

Howard: A lot of ma's stuff brings back fond memories.
Bernadette: Is that why you couldn't get rid of her drawer full of ketchup packets?
Howard: Yes. It reminds me of us eating out, and her saying "Quick, no one's looking, fill your pockets with ketchup."

Amy: Remember that time you didn't get picked to pull the sword out of the stone at Disneyland and they let that other kid do it?
Sheldon: Oh, that kid!
Poor Leonard.
Amy: Exactly.
Sheldon: For the record, that kid was a terrible choice. If you cry when you drop your churro, you do not have what it takes to rule England.

Raj: I know what it's like having to go through a loved one's possesions. My uncle was a worshipper of Krishna. But after he died, you know what we found? A statue of Shiva.
It might not be Crips & Bloods, but in India it's a thing.

Amy: Poor Leonard.
Sheldon: Why? The theory he came up with just got mentioned in Scientific American. He ought to be thrilled.
Amy: He might not be.
Sheldon: Maybe you're right. He is kind of a lump.

Amy: Sheldon, this article doesn't mention Leonard at all.
Sheldon: Oh, that can't be right.
Amy: It only refers to Dr. Cooper and his team. Did you even talk about him?
Sheldon: All I did was answer a few questions about the theory, and then express my gratitude that Scientific American doesn't include any of those smelly perfume cards.

Sheldon: And that, little lady, is Pi to a thousand places.
Amy: I'd say sorry I asked, but I didn't.
