United Nations Day jokes

He replies,"My face is so oily, I'm afraid the US would invade me."

The United Nations are putting on an event with carousels, candy floss and a ferris wheel a couple of towns away.
I wish they'd come to my town. It's UNfair.

'Who's there'
'Okay Google'
'Okay Google, who?'
'Sorry I didn't catch that'

'The World Health Organization is a specialized agency of the United Nations that is concerned with international public health. It was established on 7 April 1948, headquartered in Geneva, Switzerland. '

Why was the United Nations concerned when the waitress dropped the platter on Thanksgiving?
It meant the fall of Turkey, the ruin of Greece, and the breakup of China.

I always tell people I work for the United Nations.
It's a better way of saying I'm U.N.employed.

The United Nations world-wide survey joke

United Nations sent out a survey to every country, asking "Would you please share your honest opinion about solutions to the food shortage in the rest of the world?"

Thomas Hunt Morgan

Born 25 Sep 1866; died 4 Dec 1945 at age 79. American geneticist and zoologist famous for his experimental research with the fruit fly by which he established the chromosome theory of heredity. He discovered that a number of genetic variations were inherited together and that this was because their controlling genes occurred on the same chromosome. At Columbia University (1904-28), he began his revolutionary genetic investigations of the fruit fly Drosophila melanogaster (1908). Initially skeptical of Gregor Mendel's research, Morgan performed rigorous experiments which demonstrated that genes were linked in a series on chromosomes and are responsible for identifiable, hereditary traits. In 1910 he discovered sex-linkage in Drosophila, and postulated a connection between eye color in fruit flies and human color blindness. His study of the characteristics inherited by mutants ultimately enabled him to determine the precise behaviour and exact localization of genes. Morgan and his "fly room" colleagues, mapped the relative positions of genes on Drosophila chromosomes. Morgan published his seminal book, The Mechanisms of Mendelian Heredity in 1915. Though this work was not widely accepted initially, Morgan was awarded a Nobel Prize for physiology or medicine in 1933.
