Funeral Procession

One fall day Dave was out raking leaves when he noticed a hearse slowly drive by. Following the first hearse was a second hearse, which was followed by a man walking solemnly along, followed by a dog, and then about 200 men walking in single file.
Intrigued, Dave went up to the man following the second hearse and asked him who was in the first hearse.
“My  wife,” the man replied.
“I’m sorry,” said Dave. “What happened to her?”
“My dog bit her and she died.”
Dave then asked who was in the second hearse. The man replied, “My mother-in-law. My dog bit her and she died as well.”
“Can I borrow your dog?” asked Dave.
“Get in line.” replied the man.
