According to this Twitter update, farm animals are super in right now amongst the skinny jean set. The witness twote, "I just saw a hipster walking a sheep on Bedford Ave. So hot right now!" People, please take photos next time.
UPDATE: The sheep has been photographed... but sadly it looks like it's an "employee" of the Party Pets company, and not part of some hipster rooftop farm. So, um, who was partying with a sheep so early in the morning?
