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: Is it my fault I have a much bigger reputation than he does?
Amy: It's not your fault.
Sheldon: Is it my fault that my name came first on the paper alphabetically?
Amy: Not your fault.
Sheldon: Is it my fault that when the reporter cited me as the lead scientist, I didn't correct him?
Amy: Hey look at that pretty bird.

Leonard: I'm the one who thought of it.
Penny: Well, didn't he do a lot of the work?
Leonard: But now he's happy to let everyone think he's responsible for everything.
Penny: And that's why you get an iPad helicopter.

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.

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?

Howard: Okay, how about this? Let's invite everyone over to dinner. It'll be like Ma's feeding us one last time.
Bernadette: I love that.
Raj: Me too. Oh look, we've got enough ketchup to cover every ounce of it.

Bernadette: What should we do?
Howard: I'll tell you exactly what we're gonna do. We're gonna eat it.
Bernadette: There's like twenty-pounds of food in there.
Howard: All you said was, I had to get rid of things. You didn't say they couldn't pass through my colon first.

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.

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.

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.

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

Sheldon: I have mixed feelings about interviews. I like the part where I talk, but I do not like the part where the other man talks.

Leonard: New salon topic: What's more important-- an idea or its execution?
Bernadette: Oh, that's fun.
Sheldon: Good for you, Leonard. That's a lovely little notion. Kind of like "I wish I could talk to my uncle in Chicago." Yeah, and I'll stand back while I invent the telephone. *holds invisible telephone to ear* Hello? Oh, hold on. Leonard, it's your uncle. He says you just got burned.
