Laying Turf
A painting contractor was speaking with a woman about a job. In the first room, she said she would like a pale blue. The contractor wrote this down and went to the window, opened it, and yelled out "GREEN SIDE UP!" In the second room, she told the painter she would like it painted in a soft yellow. He wrote this on his pad, walked to the window, opened it, and yelled "GREEN SIDE UP!" The lady was somewhat curious but she said nothing. In the third room, she said she would like it painted a warm rose color. The painter wrote this down, walked to the window, opened it and yelled "GREEN SIDE UP!" The lady then asked him, "Why do you keep yelling 'green side up'?"
"I'm sorry," came the reply.
"But I have a crew of blondes laying sod across the street."

Life-form patent arguedIn 1980, arguments were heard by the U.S. Supreme Court concerning whether a patent could be issued for a genetically-engineered bacterium in the case of Diamond vs. Chakrabarty. On 16 Jun 1980, in a landmark decision, the judges held five to four that the Patent Office should recognize "any" new and useful "manufacture" or "composition of matter," and that the fact that micro-organisms are alive was without legal significance in the related patent law. Microbiologist, Ananda Chakrabarty had appealed the rejection of his 1972 patent application for a human-made, genetically engineered bacterium capable of breaking down crude oil, which no naturally occurring bacteria could do. The patent was eventually issued 31 Mar 1981.«[Image: the patented Burkholderia cepacia bacterium; inset: Chakrabarty] |
