There's a riddle going around Facebook, and the gimmick is that if you cannot answer correctly you put a giraffe photo for your profile photo. The riddle's pretty easy, as riddles go. But I hear there are a lot of giraffe photos showing.
Chatting with a friend, I happened to remember an old riddle that impressed me as a child.
You are standing on planet Earth. You walk a mile north. You walk a mile west. You walk a mile south. You are right back where you started. Where is that?
The description may sound queer
but there is such a spot on the sphere.
