wife and mother-in-law  

One fine morning a man was leaving a cafe after his morning coffee, when he noticed a most unusual funeral procession A funeral coffin was followed by a second one about 50 feet behind the first.
Behind the second coffin was a solitary man walking with a black dog.
Behind him was a queue of about 2000 men walking in a single line.
The man couldn't stand his curiosity.
He approached the man walking with the dog, "I am so sorry for your loss, and I know now is a bad time to disturb you, but I've never seen a funeral like this with so many of you walking in single line. Whose funeral is it? "
The man replied, "Well, that first coffin is for my wife. "
What happened to her? "
The man replied, "My dog attacked and killed her. "
He inquired further, "Well, who is in the second coffin? "
The man answered, "My mother-in-law. She was trying to help my wife when the dog attacked and killed her also. "
A thoughtful moment of silence passes between the two men.
Then the first one asks in excitement "Can I borrow the dog? "
The man calmly replied "Join the queue."
