Lads at a Southampton school etched a 40-foot long penis into grass using weedkiller two years ago, the Echo said. And even though teachers at the school took a dim view of the jape and re-seeded the lawn, the evidence is still clearly visible.

Not too far from Southampton at Cerne Abbas, can be found a rather larger but officially sanctioned piece of ancient graffiti - here. µ
