"Is this nonfiction? Is this just fantasy?"
The staff of the Shoalhaven Libraries in New South Wales, Australia, made a music video to celebrate the end of the school year. They not only sing, but they do a chorus line with their carts, play air guitar, and show off their books to the tune of “Bohemian Rhapsody.”
This is typical librarian behavior. Every time I go into my local library (not that I have time for books, but they have a printer), there’s someone behind the desk in costume, and usually at least a couple of people dancing. -via Metafilter
