The UK Government spy force (GCHQ) was wondering what was happening recently when their spy station aerials were picking up strange high frequency noises..
Hmm.. was it a new Osama communciation device, or aliens trying to communicate with the Government (well you never know)..
Umm.. no.. turns out it was a Ram rubbing it's horns against the aerial masts after having done a bit of servicing of the local ewes. :)
