Click on the link below. The title of the post explains it best:
"A bunch of middle-aged librarians recreated the "Sabotage" video, and the result is adorable"
One minor qualm: the original headline uses the word "adorable," whereas I think words like "amusing" and "wonderful" would have been better.
Librarians=superheroes. Only a small few in the world know what powers lie hidden beneath their mild-mannered disguise.
