For their latest stunt, Improv Everywhere reenacted a scene from Ghostbusters in the New York Public Library. From their website:
"The New York Public Library approached us about a month ago and asked if we would want to stage an Improv Everywhere mission on their property. The library is facing serious budget cuts, and they thought having us do something awesome there might serve to remind people of how great the NYPL is. We couldn't say no to the opportunity to do something in their gorgeous, 100 year-old Rose Main Reading Room." [IE]Yeah, at my library, if anyone walks in with a face mask, the patrons and librarians all speed dial the cops. If they didn't have clearance for this one, they would have been dealing with some seriously perturbed librarians.
