Yesterday, I sat upon a "U" shaped toilet seat and tried to recall if my toilets at home were "U" or "O" shaped. I decided I definitely remember them being "O" configured but I do remember growing up with "U" shaped seats when I was a child. When did the "U's" turn into the "O's" and why did this happen? Wouldn't the usage of toilet paper be more easily facilitated if seated on a "U"? (I couldn't bring myself to say wiping oneself cause that sounds gross.) Oh, the things one ponders while sitting upon a throne.
