ouch. When I was a kid in college, I heard of some guys who made a water balloon slingshot. They used it to shoot water balloons (with dye packs in them) at construction workers who were laying a cement wall. Yea, great, they were doing it out of my dorm room. And they got caught.
So, I got a call at work. I had my time card in hand, knowing campus cops would be waiting for me.
