Gill: You’re the only one small enough to get in and out of that thing. All you have to do swim inside, jam a pebble in the fan, and swim out. Once you do that, this tank is going to get filthier and filthier, and the dentist will have no choice but to clean the tank himself. He’ll put us in individual baggies, then we roll out the window, down to the ground, across the street, and into the ocean. It’s foolproof!
