Bernadette: Those tickets were pretty expensive. I had to give Howie an advance on his allowance. Now he's never going to put his toys away.

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: Why can't they do something sensible like Sheldon, and start their own comic book convention? Also, who wants to throw me out that window?

Bernadette: Well, while they're acting like teenagers we could do something grown up.
Amy: Ooh, you mean like a museum?
Penny: Yes, like a museum but anything else!

James Earl Jones: Let me guess. You like Star Wars.
*Sheldon nods*
James Earl Jones: You know I've been in other movies.
*Sheldon nods*
James Earl Jones: But you don't care about those, do you?
*Sheldon shakes his head*
*James Earl Jones signals for Sheldon to come closer*
James Earl Jones: I have one thing to say to people like you. I like Star Wars too! Care to join me?
