We all know that Japan has a lot of weirdo stuff. So when I went to Japan recently and into their toilet to take a pee, guess what I've found:

Apparently, the idea is that you will need to aim correctly when you pee and you will win the round. This way it will encourage people to aim properly when they pee and over the course of time, the toilet will be very much cleaner. It will be interesting to have this installed in Singapore toilet of course.
