A man is walking down the street when he notices an especially strange funeral procession approaching from the other direction. First comes a pair of hearses followed by a man walking a dog, then several feet behind him follows at least two hundred men, walking along quietly in single file. As the procession draws closer, the man is unable to contain his curiosity and steps along side the mourner and his canine companion. After a few moments of silence, he quietly asks "Sir, I do not mean to interrupt this solemn occasion, but I have never seen a funeral like this. Whose is it?"
"Well, my wife is in the first hearse" says the man with the dog.
"I'm terribly sorry for your loss. Who, then, is in the second?"
"My mother-in-law," says the man with the dog.
"Oh dear, I'm terribly sorry," says the man "but I have to ask, how did they both pass away at the same time?"
"Well, my dog attacked my wife and killed her. My mother-in-law was trying to help her and the dog killed her too" says the man with the dog.
A poignant and thoughtful moment of silence passed between the two men. Finally, the curious man asked, "Can I borrow the dog?"
"Sure...get in line."
