I take off my shirt and jeans, tieing them together into a lasso and manage to string my clothes around the box, back up, and pull. Because I am farther away, the bars are far enough apart to pull the box between them, and I do so, the box between the bars and holding them open, so that I may walk out. The cage wouldn't hurt the box, would it? I squeeze out and pull my lasso along with me, walking backwards until the gap is far enough apart to pull the box free, and I pull it free with the lasso, hoping I have passed its trial satisfactorily.
