How many did you catch...

A kind-hearted fellow was walking through Central Park in New York and was astonished to see an old man, fishing rod in hand, fishing over a beautiful bed of lillies.

"Tch Tch!" said the passerby to himself. "What a sad sight. That poor old man is fishing over a bed of flowers. I'll see if I can help."

So the kind fellow walked up to the old man and asked, "What are you doing, my friend?"

"Fishin', sir."

"Fishin', eh. Well how would you like to come have a drink with me?"

The old man stood up, put his rod away and followed the kind stranger to the corner bar. He ordered a large glass of beer and a fine cigar.

His host, the kind fellow, felt good about helping the old man, and he asked, "Tell me, old friend, how many did you catch this morning?"

The old fellow took a long drag on the cigar, blew a careful smoke ring and replied, "You are the sixth today, sir!"

Herbert Copeland

Born 21 May 1902; died 15 Oct 1968 at age 66.Herbert Faulkner Copeland was an American biologist who delineated four biological kingdoms, instead of just two for plants and animals. A decade after Darwin's Origin of Species, Ernst Haekel had proposed (1866) adding a kingdom, Protista, for microorganisms, but it wasn't accepted. Copeland further discriminated among the microorganisms in a paper in 1938, splitting them into two kingdoms: Monera and Protista. Copeland identified Monera as organisms without nuclei, and Protista as being largely unicellular, with nuclei. By 1956, he published a book,The Classification of Lower Organisms, still trying “to pursuade the community of biologists” to adopt these four kingdoms. Change came slowly, and continues beyond Copeland's ideas to now five or six. He was the son of botanist Edwin B. Copeland, from whom he learned the principles of classification.«
