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 phallus into the grass as an end of term joke.
Staff, parents and pupils who log on can now see the image in all its glory.
A spokeswoman for the school said: "It was just one of those high school jinks. This was an act of vandalism that took place during the summer of 2005. Southampton city council re-seeded the area and the grass was re-grown by the beginning of the new school term."
