Anti-corporate activism can be so much fun

So anyway, Wal Mart in the US were getting pissed off about all the people stealing their trolleys so they got this new high tech trolley. It's great. It has a little box that sits over the front left wheel, containing a sensor. When ever it goes over something bright yellow, it sets of the trigger which drops down the box in front of the wheel, thus stopping the trolley. So anyway, this clever, clever young boy decided this was all a bit funny but instead of figuring out how to override this function (like any mediocre hacker would), he snuck down there one night and painted a bright yellow line outside the door of the shop. HA HA HA HA HA HA!!!!!!!!! I can just imagine all these people walking out of Wal Mart with their trolley full of local income killing, sweatshop promoting, crap, destined for landfill products, heading to their SUV to empty their purchases, when THUMP. Sorry buddy, you're not going any further. HA HA HA HA HA HA!!!!!!!! I would pay to watch that.
