Mrs. Fowler: Why would Amy feel the need to lie to me?
Amy: Well, perhaps because you're her mother and she didn't want to disappoint you.
Mrs. Fowler: Really? Even after she threw you under the bus, you're still gonna defend her.
Amy: Oh, yes. She's my wife and I love her. And if I can forgive her for putting ketchup on her eggs, I can forgive her for this.
Mrs. Fowler: Her father does that, it's disgusting.
Sheldon: Amy's crazy, you are a delight.
