Today's Education Supplement in UK newspaper The Guardian carries the following story:

"Two pupils who drew a giant penis on a school lawn using weed killer two years ago can still admire their work from satellite photos now posted on the internet.

Despite the school re-seeding the area, the penis has turned up on satellite image search engines because a photo was taken before the new grass could conceal the appendage.

The unnamed pair of year 11 pupils from Bellemoor school for boys in Southampton, burned the 6-metre (20ft) phallus into the grass as an end of term joke."

Our own little NCEA tagger was obviously thinking much too small.
