Back in the good old days of the V force when RAF policemen guarded aircraft I met an RAFP dog handler who was in love with his dog. he was convinced it was cleverer than Einstein. Well, it was cleverer than its master! One warm summer night he was chatting with a few of us linies, and he showed us the dog's latest trick. He pulled out his pistol, pointed it a the dog, and said "Bang". The dog fell down and rolled on its back with its feet in the air
