Bernadette: It smells pretty ripe in here. You kinda feel it in your eyes.

Howard: I'm sorry I didn't take you to the airport. I just want you to know I'll never forgive myself for being so selfish. And I promise to keep you close for the rest of my life.
Bernadette: Oh, no, that thing's gonna end up in my bedroom.

Bernadette: (Shouting from the bathroom) How many times do I have to tell you to replace the toilet paper when it's empty?
Howard: I'm in the middle of something.
Bernadette: So am I!

Bernadette: Gosh, Amy. I'm sensing a little hostility. Is it maybe because like Sheldon's work, your sex life is also theoretical?

Sheldon: She's remarkable.
Leonard: She really is.
Sheldon: How is it that she can remember all those lines, yet as a waitress she can't remember no tomato on my hamburger?

Lucy: I'm kind of broken.
Raj: That's great. I'm broken, too.
Lucy: Oh, no you're not.
Raj: Oh, I totally am. If it wasn't for this beer, I couldn't even talk to you right now. I'm a wreck. There are many things seriously wrong with me. And not quirks, either. Like diagnosable psychological problems. Maybe brain damage.
Lucy: Well how do I know you're not just saying that?
Raj: Go out with me on one date. I promise you, you'll see.

Raj: My heart is stone. From now on, I'm a monk. I renounce all worldly pleasures. Except for lobster. And garlic butter.
