So, you are bored at work. What is there to do? Well, you could decorate the glass walls of your office building with Post-it pictures of your favorite animated characters. This is exactly what employees at Ubisoft Montreuil in France did. But, their neighbors across the street at BNP bank took their Post-it artwork as a bit of a challenge, and started firing back with some window images of their own. Thus, the Great French Post-it War of 2011 was born. Clearly, it spawned an epic rivalry worthy of the likes of Mario and Bowser. Check out the pictures from their Post-it battle below.
