I went to a college where our archrivals were right across the street. Every year during our homecoming the usual pranks would take place: painting the mascot statues, soaping the fountains, paintballing the coeds etc... The year before I went down there a few guys in my frat/flight program decided to pull a prank fly boy style. They took up four 172's with a bunch of gallon cans of paint in our school colors and proceeded a bombing run on the rivals stadium. They exploded on the field, bleachers, and track and made a very colorful scene to say the least. They also never got caught.
