Fred and Bob went deer-hunting. Sadly, Bob got accidentally shot and fell in a crumpled heap. In a panic, Fred got out his phone and called the emergency services. "My friend's been shot!", he yelled, " Looks like he's dead!"
"Now don't panic," said the calm voice on the end of the line, "We're here to help you. But first of all, just make sure he really is dead."
There was a loud bang. "OK", said Fred, "What do I do next?"
