Requesting A Three Day Pass

An Israeli soldier who just enlisted asked the Commanding Officer for a 3-day pass.
The CO says "Are you crazy? You just join the Israeli army, and you already want a 3-day pass? You must do something spectacular for that recognition!"
So the soldier comes back a day later in an Arab tank!
The CO was so impressed, he asked "How did you do it?"
"Well, I jumped in a tank, and went toward the border with the Arabs. I approached the border, and saw an Arab tank. I put my white flag up, the Arab tank put his white flag up. I said to the Arab soldier, "Do you want to get a three-day pass? So we exchanged tanks!"

Ruth R. Benerito

Born 12 Jan 1916; died 5 Oct 2013 at age 97.Ruth Rogan Benerito was an American chemist who was a pioneer in the development of wash-and-wear fabrics. Earlier, she investigated fat emulsions and transport of fat in animals. For the Office of the Surgeon General, she developed an intravenous fat emulsion for intravenous feeding to help supply necessary calories for long term patients. Benerito also investigated the reaction epoxies. Her findings have been used not only in the textile industry but also to paper, film, and epoxy plastic manufacturers, and they have been applied in the use of epoxy compounds to preserve wood. Benerito has been granted over 50 patents. Her research has resulted in the development of cotton fabrics that are comfortable, wrinkle-free, stain resistant, “drip-dry” and better able to retard flames.
