A Topologist’s Blessing
hover here for larger image
If you are not simply connected, that is, if the Genus of your personal manifold is not 0, then either you are not in one piece or you've got a hole in you—which would not be good! So, display this blessing that all may know how much you value being isomorphic to a sphere. (That's isomorphic, not isometric!)
Now, before any of you topologists rush to correct us—yes, we know that there is a tube running through us end-to-end, and so, strictly speaking, we are Genus 1. If you insist on pointing this out we shall be forced to purse our lips. There, no more tube.
