Insane Clown Posse Reference in Ubisoft's Watch Dogs

We have been hit up with a few emails and even messaged on Facebook about this tidbit of information. In the new Ubisoft video game Watch Dogs there is a small reference to Insane Clown Posse. There are some digital billboards that feature the question Magnets, How Do They Work?. You can see a screen cap of the billboards on the right side to the page.
