This is a bathtub plug with a little floating fob in the shape of a man—the aforementioned Mr. Suicide. What is the cultural significance of such a delightful little reminder of our own morality? I don't know. However, he looks big enough not to get lost when you're washing the boys or girls.
Senor Suicide, as he is known in Spain, is available for $25 from YankoDesign.
