I have been to many places and seen many things. Not everywhere and not everything, of course. I’ve never lived in the Hamptons, for instance, and I’ve never personally seen the back bar at the ale house in Louisville, for another. Today I am Washington, D.C., a city I’ve been to before—four times? five? I don’t recall exactly—and I have just seen something I’ve never seen before: a showerhead apparently designed to meet the challenge of getting one’s belly button really clean.
