A prank at a Hamilton school showing six penises etched into the grass has been caught by satellite.
The Fairfield College phalluses were snapped from space and used to compile the Google map used by millions of web browsers daily.
The satellite pictures were taken in May 2009.
David McQuoid was searching for a property when he came across the surprising snaps.
"At first I thought it was a large piece of art work."
But acting principal Gerhard van Dyk was not amused and said he would like to have caught the culprits.
Unfortunately, the incident happened on a weekend.
By Monday, van Dyk said the caretaker became aware of some of the grass dying, as the x-rated crop circles popped up around the school.
"There's not really much we could do about it," he said. "The caretaker took some more weedkiller and tried to camouflage it a bit."
The rest of the grass was killed, but it was a few months before the rude renderings disappeared. But by then the Google satellite had snapped the images.
Van Dyk said he would contact Google.
A spokesperson for the internet giant said the Earth images came directly from satellite pictures, unlike the Google Street View shots, which could be blurred for privacy reasons.
Netsafe executive director Martin Cocker said he had heard about similar instances of people trying to find infamy but things hung around a lot longer on the web.
