Yesterday when we saw this picture of a funny sign attached to a tree in Greenpoint, we thought: "Heh, look. A funny sign attached to a tree in Greenpoint." And then we moved on. But today we saw it again, and we realized there is way more going on in this picture than just a clever warning. Is that a Sad Puppy in the background? And is he sad because he got called a mutt? (Or a slut??) [Newyorkshitty]
