Sheldon: Thank you for the invitation, but I have to decline because it doesn't sound like something I'll enjoy.
Leonard: Come on, Sheldon, it'll be fun.
Sheldon: That's what you said about The Green Lantern movie. You were 114 minutes of wrong.

Bernadette: Howard Joel Wolowitz, like you, this is going to be short and sweet. I love you with all my heart and soul and promise to be with you forever.
Howard: Bernadette Maryann Rostenkowski...
Mrs. Wolowitz: Speak up!
Howard: Hey, from now on, she's the only women who can yell at me!

Mike: Hey, Froot Loops, want to hit your fan switch?
Howard: Check.
Dimitri: He calls you Froot Loops because of your very gay haircut?
Howard: No, it's 'cause I live with my mom and she makes me Froot Loops.
Dimitri: Go with gay story, people are more accepting of that.

Mike Rostenkowski: Last murder case before I retired. How many bodies do you see there? Careful, i's a trick question.
Howard: Im not sure.
Mike Rostenkowski: Nah, you'll never get it. It's a fraction.

Amy: We'll see. Let's start with a little romantic dinner music, shall we?
Sheldon: Super Mario Bros. theme?
Amy: Yes.
Sheldon: I see what you're doing. You're attempting to build on the work of Ebbinghaus by triggering an involuntary memory of me playing that game, admittedly the happiest 600 hours of my childhood, but it won't work.

Sheldon: Oh! A tissue! A tissue! Oh, good Lord!
Assistant: Uh, where's he going?
Leonard: He keeps emergency Purell in the car.
Sheldon: Keys! Keys! Keys!

Raj: Well, that wasn't as entertaining as when he rents bowling shoes, but it was right up there.

Mr. Rostenkowski: Walnut?
Howard: No, thank you. I'm allergic.
Mr. Rostenkowski: Oh, sure. My partner used to have that. He's dead now.
Howard: From nuts?
Mr. Rostenkowski: Nah, his wife shot him. But she was nuts, so in a way.

Sheldon: For example, this morning I was calculating the random motion of virtual particles in a vacuum, when suddenly the particles morphed into an image of Amy's dandruff gently cascading down onto her pale, slightly hunched shoulders. Oh, what has that vixen done to me, Leonard? And how do I make it stop?

Amy: Oh, I know. I think it will go nicely with what I have prepared for dinner.
Sheldon: Spaghetti with little pieces of hot dog cut up in it!
Amy: Just like your mommy used to make.
Sheldon: Oh yummy, yummy! We should do this more often. Uh-oh.

Sheldon: I assume we're talking about you now?
Leonard: Yeah.
Sheldon: So that's how this works, I complain and then you complain and no one offers any solutions?
Leonard: Pretty much.
Sheldon: Well no wonder the women are winning.

Mr. Rostenkowski: It's gonna be okay, son.
Howard: You really think so?
Mr. Rostenkowski: Of course. A pretty girl like Bernadette, she'll find a new guy.

Sheldon: Ah, much better.
Leonard: You must be burning up.
Sheldon: A little. But not more than your urethras will be after whatever's in those pants swims up them.

Sheldon: Well, I cut quite the dashing, yet hygienic figure, don't I? I look like the Flash about to get married.

Amy: Human beings form emotional attachments as they grow up. In your case, to your mother, superheroes, et cetera. I'm going to attempt an experiment that will get you to transfer those feelings to me.
Sheldon: Well, it seems what's on the menu tonight is malarkey with a big side of poppycock.
