On a sunny Saturday, all I can say is please enjoy some random photos from bathroom stalls. In no other country have I seen as many weird signs in bathrooms as in Taiwan. This deserves to be noted - celebrated, even.
Why would you throw a hot dog into the toilet?
Purple - OK. Maybe you ate too much red dragonfruit. The grayish color could be baby poop. But if your poo is bright orange or red, shouldn't you see a doctor?
