Bernadette: Sheldon, I've been cooking all day.
Sheldon: Well, now don't you feel silly.
Bernadette: (To Howard) Show him the closet.

Bernadette: You better find my husband's mother, 'cause one way or another we're walking out of this airport with a dead woman.

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?

Sheldon: Did you also have a dog? Because I found what appears to be a battery-operated chew toy.
Penny: Party's over. Party's over.

Bernadette: I told you you shouldn't have espresso after dinner. I know the little cups make you feel big but it's not worth it.

Bernadette: You can't just throw everything in the closet.
Howard: Hey, you can tell me what to do and how to do it, but not both at the same time. This isn't sex.
