You know the joke about how when you kiss someone, you’re temporarily forming a long tube with an anus at each end? A topologist friend heard that joke and immediately offered a conjecture that that shape is topologically equivalent to the shape you’d get if you connect a mouth to an anus. This got the party discussing if there exists a homeomorphism between making out and eating ass. I agree, you really can’t trust topologists.

It doesn’t exist, because there is no homeomorphism that takes a distance of 0 to non 0, so you can’t change the connections.

  But still, the two forms are the similar (same amount of holes). Do you have to view them with a color gradient to consider them different?

  I suspect the real reason for her making that conjecture was to nerd snipe a bunch of professors into discussing eating ass

Topologically a human is a donut (torus).

  I think humans probably have a variety of tubes at various sizes that complicate the analysis.
