The Birthday Synchronicity
Bernadette is in labor, so the guys put a plan in motion to drive her to the hospital, with Raj at the wheel.
Meanwhile, Sheldon wakes Amy up to tell her happy birthday and give her a present. They are just about to have sex when they get the call that Bernadette is having the baby, so they put things on pause and get ready to go to the hospital with the rest of the gang.
At the hospital, Bernadette is sent home because her contractions are still too far apart.
Raj records video and accidentally lets slip that the baby is a girl, so Howard and Bernadette kick him out.
Sheldon and Amy go back home, and Amy breaks out two Harry Potter costumes to help get them both back in the mood. They are interrupted again wih the news that Bernadette's water has broken.
Everyone waits in the waiting room while Bernadette is in labor, and Raj feels bad that his friends are upset with him.
But when the baby is born, Howard makes an announcement that makes Raj feel better.
The gang is happy to hear that the baby has arrived, and they go peek at her in the nursery.
