Jon left for a two day busines...

Jon left for a two day business trip to Chicago. He was only a few blocks away from his house when he realized he'd left his plane ticket on top of his dresser. He turned around and headed back to the house. He quietly entered the door, walked into the kitchen. He saw his wife washing the breakfast dishes, wearing her skimpiest negligee.
She looked so good that he tiptoed up behind her, reached out, and squeezed her left tit.
"Leave only one quart of milk," she said. "Jon won't be here for breakfast tomorrow."

Alfred Day Hershey

Born 4 Dec 1908; died 22 May 1997 at age 88. American biologist who, along with Max Delbrück and Salvador Luria, won the Nobel Prize for Physiology or Medicine in 1969. The prize was given for research done on bacteriophages (viruses that infect bacteria). This was the famous “blender experiment”(1956). Hershey used an isotope- labeled phage to to infect a bacterial colony and begin to inject their genetic material into the host cells. Then he whirred them in a Waring Blendor to tear the phage particles from the bacterial walls without rupturing the bacteria. Upon examining the bacteria, Hershey found that only phage DNA, but no detectable protein, had been inserted into them. This showed that the DNA was sufficient to transfer to the bacteria all the genetic information needed to produce more phage.
