Banksy?

So a few weeks ago I was home and decided to visit one of my favorite places in RI.  Thayer Street is a local attraction for many Rhode Islanders, Brown University students, visitors interested in Historical RI, etc.  I am pretty sure we all took Theatrical Design last year with Frances, and there was a section where we went through different artist, designers, architects, and so on.  Well, while walking down Thayer Street I am pretty sure I nearly gave a my parents a heart attack when I stopped, turned around, and screamed "ARE YOU KIDDING ME!?!?"  Spray painted on the wall of a local building was this:
