The latest Improv Everywhere stunt unfolded recently on the 23rd Street E and C line subway platform: a pop-up art gallery with placards attached to everyday items, magically transforming them into priceless works of art. The trash can, for example, was titled Repository and described as a "clearly ironic reinterpretation" that "plays on the tropes of idealism in opposition to expediency." There was also a bar (stocked with non-alcoholic drinks), a cellist, and even a coat rack. Fancy!
