A family friend back home lived next door to a wealthy couple who were massively obnoxious Tahd fans. The week of the Bo Over The Top Game, they had done some landscaping and resodded their entire front lawn. which was on a fairly large slope. After AU's win, James crept over in the middle of the night, and with a spray container full of liquid fertilizer, wrote "WAR EAGLE" in their new grass on that slope. Of course, it being winter and all, only that area sprouted a bright vivid green - you could read it from the road. Once the wife realized what it said, she took a rototiller and demolished every bit of their brand new sod.
THAT is how you do it...
