Slight thread drift but ISTR a post on here that a bunch of Lineys did much the same when they built a snowman outside their hangar and patrolling Plod in their landrover came round and deliberately demolished it by driving through it..
The snowman was rebuilt, just this time around a concrete bollard, and the lads awaited Plod's return .. And they were not disappointed with the results
Nothing new under the sun. In "Biggles Goes to School" he paints a cannon ball to look like a football(?) and leaves it in the path of a master who, he knows, can't resist kicking a ball. Obviously the start of a RAF tradition.
