Sheldon: Yeah, I have to say, it is nice to share this experience with someone who's on the same journey. Although right now ours is testing off the charts while yours is floating around in its own waste.
Bernadette: Are you actually comparing my human baby to your brain in a bowl?
Sheldon: Well, I didn't make you waddle up four flights of stairs for the heck of it.
Bernadette: You do realize my baby has functioning organs and can recognize voices.
Sheldon: Yeah, but ours can recognize a specific data stream among background noise.
Bernadette: Mine has a fully developed immune system.
Sheldon: Ours doesn't need an immune system because it lives in a state-of-the-art German incubator.
