We took a trip to North Carolina a couple of years ago and rented a car that had what I thought was a novel feature.
I'm not exactly sure how this works and the cat was distinctly uncooperative when we asked her to help us figure it out. She probably noticed that the illustration indicates that her little ears would end up going in different directions. Although I still don't know the precise function of the cat folder, I'm pretty sure that the family in A Good Man is Hard to Find would have been better off had they had one.

This is the inside door of the restroom at work.
After they put the sign on the left up, it was amusing to watch women leaving the room with a puzzled look on their faces. One of the newer employees came to my office and said in a low voice, "Uh, can I ask you something? What does the sign in the restroom mean?" Well, we never could quite figure out how to comply and eventually the sign came down and now everyone that might have been responsible for it has moved on.
Nobody ever asks about the sign on the right, but I frequently wonder if there is anyone who has figured out how to leave the restroom without opening the door. I've been tempted to try it myself, but haven't yet worked up the courage. Most of our students are ministers, so I guess they might think that since Jesus walked through walls, we should do likewise. I'm just trying to figure out whether you should try exerting a slow, steady pressure or if you need to charge through the wall like at platform 9 3/4 at Kings Cross Station.
