Starbucks stores seem to pop up like pimples on a hormonal teenager. Every time you turn around, there’s another one bigger than the last.

Most of us love their caffeinated beverages, and most of us probably drink more of them than we should. But none of us have consumed as much Starbucks as New Yorker, Mark Malkoff.

In this video, he attempts the seemingly impossible: to visit every Starbucks in Manhattan in one day. With a whopping 171 stores spread across the city, it was never going to be easy.

I won’t spoil it for you by telling you whether he makes it. But I will say this: drinking a whole lot of coffee does strange things to a man. I can’t work out whether this video is inspirational, crazy, or both.
