True fact: I once drank a vaseful of coffee.
In my defense, the vase was rather small as vases go, and could (if one squinted) have been mistaken for an especially large novelty mug. And it was sitting in the cupboard alongside many other mugs. However, I was assured by several people in my office’s break room that it was a vase, and had come with a little arrangement of flowers the practice had received.
I didn’t care. I filled it up with coffee and took it to my desk anyway.
