Moths

A woman was having a passionate affair with an inspector from pest-control company. One afternoon they were carrying on in the bedroom together when her husband arrived home unexpectedly. "Quick," said the woman to her lover, "into the closet!", and she pushed him into the closet stark naked. The husband, however, became suspicious and after a search of the bedroom discovered the man in the closet. "Who are you?" he asked him.
"I'm an inspector from Bugs-B-Gone," said the exterminator.
What are you doing in there?" the husband asked.
I'm investigating a complaint about an infestation of moths," the man replied.

Joachim Barrande

Born 11 Aug 1799; died 5 Oct 1883 at age 84.French geologist and paleontologist. He settled in Prague (1832), at first as an engineer. While surveying the proposed route for a horse-drawn railway, he became interested in the local fossil-bearing rocks there. From 1840, he turned to the study of these fossils in the strata of the central Bohemian basin. In his lifetime, he gathered some 3500 species of graptolites, brachiopoda, mollusca, trilobites and fishes, showing a wide variety of life forms in the Early Paleozoic era. (The Paleozoic era spanned 540-245 million years ago.) He meticulously recorded his findings in Système silurien du centre de la Bohême, which remains a fine reference work. The first volume was published in 1852, and was followed by 20 more in his lifetime. He opposed Darwin's theory of evolution, instead advocating the theory of catastrophes.«
