One day a man notices a funeral procession. It's headed by two hearses, followed by a man with a large dog, and then by a file of people that stretches nearly a quarter of a mile. "Who's in the hearses ?", he askes the man with the dog. "Oh, the first has my mother-in-law in it and the second, my wife". "How did they come to die then ?", asks the first man. "Well my mother-in-law nagged me, the dog bit her, and she died the next day - then my wife nagged me to get rid of the dog and it bit her - she died the following day". The first man thinks for a bit and then asks "Would you lend me that dog ?". "Join the end of the queue", said the man with the dog.
