 FAKE: When Andy goes to Otis cell to bring him a cup of water, he  retrieves the cell keys from the wall between the cells where they  are usually kept, opens the cell door and leaves the keys in the  door. After giving Otis the water, he shuts the cell door, leaving  the keys in it. He then returns to the back office. When Otis calls  Andy again, this time implying a request for Andy to quote him Jack  and the Beanstalk, Andy walks from the back office to the cell  door, and again reaches up to the place on the wall where the keys  are usually kept, opening the cell door with them.
