Any New Yorker has run into the giant inflatable rats used by unions to picket businesses with which they have a grievance. These rats have long been made and sold by inflationists like Big Sky Balloon & Searchlight, which supposedly created the first rat for a Chicago union and still makes several of the models familiar to us all today. Perhaps most common is the traditional "festering nipples" rat, which cuts an impressive figure at 20 feet tall. However, NYC unions protesting Beth Israel Medical Center at 1st Avenue and 16th Street are taking it to the next level with this colossal 30-foot rodent. That thing is Macy's parade huge; it's easily tall enough to sneer directly into the second-story windows. No word on nipples, festering or otherwise.
