Penny: All right, it's got to go.
Bernadette: What will you tell Amy?
Penny: How about I tell her the painting makes you feel jealous because you're not in it?
Bernadette: Nuh-uh. What if she gets me one? I already have a picture of me and Howard's mom getting our hair cornrowed in Venice Beach. I've suffered enough.

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: I'll let you in on a little secret. Originally, we were painted nude. But I had him add clothes cause I thought it was an unnecessary challenge to our heterosexuality.
Penny: Yeah, good call.
Amy: But, if you ever change your mind, all it would take is some warm, soapy water and a couple of sponges.
Penny: You're talking about the painting, right?
Amy: Sure.

Sheldon: I'm trying to raise the temperature in here before my nipples tear through my shirt.

Penny: It's kind of heavy.
Bernadette: Too bad you're not as strong as the dude in the painting.
