Today is John Green Day!

Jason English

You may know John Green from one of his hugely popular YouTube shows (like ours!), or for his best-selling novels, or for selling out Carnegie Hall with his brother, or from the time he asked President Obama for baby-naming advice. But way before all that, he wrote for a tiny new magazine based in Birmingham, Ala., called mental_floss. And today we'll be celebrating our most famous alum!

The good people at Penguin Young Readers hired us to promote the new edition of John's latest, The Fault in Our Stars. So we've declared today John Green Day. 

(Happy John Green Day!)

We'll have stories from John, about John, about writing, and more. Let's get started with a list of amazing facts we've learned from John's various YouTube shows.
