Improv Everywhere, known across the Internet for seemingly-random outbursts of public hilarity, has taken up the cause of helping the New York Public Library stay afloat by making a Ghostbusters-inspired appearance that was completely unexpected by those in the library trying to get some reading done:

From improveverywhere.com:

For our latest mission, we brought the movie Ghostbusters to life in the reading room of The New York Public Library at 42 Street. The 1984 movie begins with a scene in the very same room, so we figured it was time for the Ghostbusters to make an encore appearance.

Only a handful of library workers (along with those who shot the event on their DSLR cameras) were in on it. Everyone else in the library was completely surprised by the team of Ghostbusters chasing white-sheeted ghosts through the famous movie location.

Their behind-the-scenes write-up tells the whole story of how it all came together and includes a great photo series depicting smiles on almost all of the onlookers’ faces. I only wish I could have been there because bustin’ like this certainly makes me feel good.
