Two Hearses

One fall day, Dave was out raking leaves when he noticed a hearse going down the street, followed by another hearse, 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 who was in the first one:

- My wife - the man replied.

- I'm sorry - said Dave.

- What happened to her?

- My dog bit her and she died.

Dave was taken aback.

- And who's in the second hearse?

- My mother-in-law. My dog bit her too and she died as well.

Dave asked:

- Can I borrow your dog?

- Get in line.
