A family is at the dinner table. The son asks his father, "Dad, how many kinds of boobies are there?
The father, surprised, answers, "Well, son, there's three kinds of breasts. In her twenties, a women's breasts are like melons, round and firm. In her thirties to forties, they are like pears, still nice but hanging a bit. After fifty, they are like onions."
"Onions?"
"Yes, you see them and they make you cry."
This infuriated his wife and daughter so the daughter said, "Mum, how many kinds of 'willies' are there?"
The mother, surprised, smiles and answers, "Well dear, a man goes through three phases. In his twenties, his willy is like an oak tree, mighty and hard. In his thirties and forties, it is a birch, flexible but reliable. After his fifties, it is like a Christmas tree."
"A Christmas tree?"
"Yes, dead from the root up and the balls are for decoration only."

George R. Carruthers

Born 1 Oct 1939.Black-American astrophysicist who was the principal inventor of a new space camera to measure ultraviolet light which can be used to identify interstellar atoms and molecules. After several years in development, it was taken to the moon on the Apollo 16 mission (1972). Positioned on the moon's surface, the camera could also image the gases of the Earth's atmosphere. The concentration of the pollutants, such as carbon monoxide, in the air surrounding large cities could be determined for many cities at the same time. Other space cameras developed by Carruthers and his colleagues have surveyed the ozone layer and transmitted photos of distant stars and planets for computer analysis. He also pioneered in the development of electronic telescopes.
