  On the one hand, it’s a joke … on the other, it is an interesting epistemological question (I know, I’m an ass for using such a word): What makes you think coffee isn’t a food? What’s the difference between food and drink? 😛
  
  I’ll change my answer to sour-dough pizza if you can persuade me coffee isn’t food 🙂
