Good doggie

One fall day Bill 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, Bill 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 Bill. "What happened to her?"

"My dog bit her and she died."

Bill then asked the man who was in the second hearse. The man replied, "My mother-in-law. My dog bit her and she died as well."

Bill thought about this for a while. He finally asked the man, "Can I borrow your dog?"

To which the man replied, "Get in line."

Alexis Bouvard

Died 7 Jun 1843 at age 75 (born 27 Jun 1767).French astronomer who was the director of the Paris Observatory, and is noted for discovering eight comets and writing Tables astronomiques of Jupiter and Saturn (1808) and of Uranus (1821). Bouvard's tables accurately predicted orbital locations of Jupiter and Saturn, but his tables for Uranus failed, leading him to hypothesize that irregularities were caused by an unknown perturbing body. This spurred observations leading to the discovery of Neptune by Adams and Leverrier.
