It’s December 1, which means it’s officially time to freak out about whatever winter holiday you celebrate. (Unless you’re proactive like me; I’ve been freaking out for weeks now.) Here are a few cards to get you in the holiday mood.

Holiday Cards for Geeks – Includes sentiments like, “May all your Christmases be #FFFFF,” and cards featuring the Flying Spaghetti Monster and LOLCats.

Isaac Newton – Major amusement for geeks and atheists alike.
