The Two Reasons Why

I've noticed the strangest thing about men who hang out in bars a lot.
It seems they have only one of two reasons to be there.
They have no wife to go home to... or they do!

James Challis

Born 12 Dec 1803; died 3 Dec 1882 at age 78.English astronomer and clergyman, famous in the history of astronomy for his failure to discover the planet Neptune. Astronomer and mathematician John Couch Adams had studied the known deviations in the orbit of the planet Uranus which indicated a planet even further out. In 1845, Adams gave Astronomer Royal George Airy a calculated orbital path for the unknown planet. But Airy was more interested in the primary job of navigation and timekeeping observations. Airy informed Challis, who did not begin until July 1846, and actually sighted the new planet four times without recognising it. On 23 Sep 1845, the new planet was instead discovered from Berlin Observatory. Challis admitted that Adam's prediction was within 2° of the planet's position.
