Bernadette: Are we being silly not finding out the sex?
Howard: Yeah, I was just thinking the same thing.
Raj: If you want, you can find out right now.
Bernadette: Hmm. The doctor's gone for the day, so it doesn't matter.
Raj: Or somebody else knows because they saw it in the folder.
Bernadette: You looked in our folder?!
Raj: It was an accident. The doctor left the folder out on her desk. It's not my fault I opened it and looked.
