Strange funeral procession

A Man was leaving a 7-11 with his morning coffee when he noticed a most unusual funeral procession approaching the nearby cemetery.

A long black hearse was followed by a second long black hearse and behind that was a solitary man walking a pit bull dog on a leash with 200 men behind him walking single file.

The man couldn't stand the curiosity so he respectfully approached the man walking the dog and said, "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. Whose funeral is it?"
The man replied, "Well, that first hearse 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 hearse?"
The man answered, "My mother-in-law. She was trying to help my wife when the dog turned on her."
A poignant and thoughtful moment of silence passes between the two men."
Can I borrow the dog?"
"Get in line."
