Howard: I love that I'm a slob around here and you're kinda okay with that.
Bernadette: Uh-huh. And I love that I work and do all the cleaning and you're okay with that.

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?

Amy: This is an easy one. You love this guy.
Sheldon: Me.
Amy: Come on. He's an under appreciated genius.
Sheldon: Still think it's me.
Amy: It's not you. Now think, there's a car named after him.
Sheldon: Of course there is. The Mini Cooper because it's me.
Amy: How about this? He's a poor man's Sheldon Cooper.
Sheldon: Oh, Tesla.

Raj: I'm sorry I'm so late. I was on the phone with my mother.
Bernadette: How is she?
Raj: Pretty good. She bought the book "Eat, Pray, Love", and used it to set my father's Mercedes on fire.

Raj: So, what's up with you guys?
Howard: We're just saying all the things we love about each other.
Raj: Oh, like you and I did at couple's therapy?
