Microsoft boss Bill Gates has launched a counter strike against the gaggles of incontinent geese dumping daily on his hi-tech mansion in Lake Washington.

Gates has asked the local parks department to rustle up the aerial protestors and run them out of town, and the chief park ranger now has permission to exterminate more than 4,000 of the flying dumpsters.

The parks department has been quick to point out that the move to kill the geese has not been undertaken solely as a result of Gates's complaints.

It said that tourists need to be protected on the area's beaches, which were being ruined by the guano carpet bombing.

According to the Seattle Times the geese are achieving what penguins could not and are dumping more than three pounds of waste a day on mansions in the area.
