How did I miss "National Coffee Day" yesterday?

Obvious Answer: I didn't have enough coffee. 

In belated celebration, here is a link to The Oatmeal's 15-ish Things Worth Knowing About Coffee.

One addition from your host: it wasn't just Charles II who closed coffee houses--the Ottoman Sultan Murad IV earlier banned coffee because of its association with subversive elements. He even had people executed for violating the ban--sometimes doing the killing himself. 

Murad IV: Not known for his whimsy.

Harsh. 

Then again, I imagine caffeinated Janissaries could be difficult to manage.
