Holycrapspiders

So, I'm on a jumping spider kick right now:

Watch as Scientist Fred Armisen (much like Astronaut Barbie) explains the courtship behaviour of jumping spiders (who, he says, are "more than just a pretty face"). You guys, they dance AND sing. It is both horrifying and FASCINATING.

If you liked this, I'd highly recommend these videos:
