Sheldon: Look, I'm sorry. Tell me why Bernadette is upset with you.
Penny: Well, I told people at work that she's pregnant. She wasn't ready for them to know.
Sheldon: Why would you do that?
Penny: Well, it just slipped out. I feel terrible.
Sheldon: See, that's exactly what happened to me, except that I said it on purpose, and I have no regrets.
