Raj: What, y-you stole our Bitcoin?
Sheldon: Oh, calm down. All I did was sneak onto your computer and download your Bitcoin onto a flash drive.
Sheldon: I'm not keeping it. I just wanted to watch you sweat.
Howard: If you want to watch him sweat, walk up a flight of stairs with him.
Sheldon: I've waited seven long years, but it finally happened.
Leonard: Where's our money?
Sheldon: That's the best part. It's on the Batman flash drive on your key chain. You've had it in your pocket all along.
Leonard: Sheldon I lost that key chain years ago.
Sheldon: Really? D-D-Did you look under things?
