Two friends were out hunting, when suddenly one of them puts his hands up to his chest and collapses on the ground. His eyes are glazed and his friend, who is very concerned, can feel no pulse. He finds his mobile phone and dials 999 (191) The operator answers.....' It's my friend, he's dead I think....Need help...must be a helicopter.......... 'Calm down' say's the operator, 'You mustn't panic. Now the first thing you must do is to make sure that he is in fact dead.' 'Yes, you're right....hang on' say's the friend. The operator waits a few seconds and then hears 'BANG ! BANG ! ' OK' say's the friend, 'Then what?'
