October 21, 2013: The class Reptilia is pretty cool, encompassing turtles, crocodilians, snakes, lizards, and a few other cold-blooded egg-layers. Reptile Awareness Day is meant to shine a light not only on how groovy they are, but also their habitat loss and threat of extinction. On a lighter (and yet more fattening) note, International Nacho Day should bring us all together in a worldwide celebration of delicious food on chips. I believe there’s also a National Nacho Day coming up, because we Americans have to have our own stuff. Lastly, I’d be a very bad geek indeed if I missed Carrie Fisher’s birthday; the hair-buns alone will stand forever as a sci-fi staple. And if there’s ever a convention without a girl in a Slave Leia costume, I’ll eat my hat.
