Raj: I appreciate the apology, but it's really not necessary. I overstepped my bounds.
Howard: No, Raj, you've been great. I just, I need to start doing my part around here.
Bernadette: I hear 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: Gosh, Amy. I'm sensing a little hostility. Is it maybe because like Sheldon's work, your sex life is also theoretical?

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: He's just trying to be supportive.
Howard: Just supportive. Not over-the-top in any way?
Bernadette: No.
Raj: Hello. (Raj walks in with a gigantic teddy bear)
Bernadette: You saw him carrying that?
Howard: Astronauts saw him carrying that.

Penny: I'll see if it's available.
Amy: You know, if that study's real, Leonard might come back smarter than you.
Sheldon: Are you trying to manipulate me?
Amy: Yes.
Sheldon: Well done, it worked, we're going.
Amy: Yay!

Raj: Of course. I'll give you guys some space. Let me just get this out of your way. (Raj fumbles around trying to move the gigantic teddy bear. He knocks over various objects in Howard & Bernadette's living room)
Howard: You need some help?
Raj: No, I got it.
Bernadette: Raj, Raj, wait.
Raj: Please, Bernadette. Let me leave with my dignity. (Raj falls over the teddy bear as he tries to move it out the door)
