Since the Japanese have long believed that ghosts hang out in bathrooms, an enterprising writer has started printing ghost stories on toilet paper. The idea is that you can read a story while you wait for your movement.

While the concept is novel, I would think it to be counter productive. It might work if you lived by yourself. But knowing that the next chapter may go missing before you get to read it, might encourage longer stays.

But then again, some people have too much time on their hands.
