"A Dog's Life" joke

A man was leaving a Stop n' Go with his morning coffee and newspaper when he
noticed a most unusual funeral procession approaching the nearby cemetery. A
long black hearse was followed by another long black hearse about 50 feet
back. Behind the second hearse was a solitary man walking a pit bull on a
leash. Behind him were 200 men walking single file.
The guy couldn't stand the curiosity. He respectfully approached the man
walking the dog and said: "Sir, I know now is a bad time to disturb you, but
I've never seen a funeral like this. Whose funeral is it?"
The man replied "Well, that first hearse is for my wife."
"What happened to her?"
The man replied "My dog bit her and she died."
He inquired further, "Well, who is in the second hearse?"
The man answered, "My mother-in-law. She was trying to help my wife when the
dog turned and bit her and she died."
A poignant and thoughtful moment of silence passes between the two men.
"Sir, could I borrow that dog?"
"Get in line."
