Try Nursing!

A very well-built young lady was lying on her psychiatrist's couch, telling him how frustrated she was.

"I tried to be an actress and failed," she complained. "I tried to be a secretary and failed, I tried being a writer and failed, then I tried being a sales clerk, and I failed at that too."

The shrink thought for a moment and said, "Everyone needs to live a full, satisfying life. Why don't you try nursing?"

The girl thinks about this, then bares one of her large, beautiful breasts, points it at the shrink, and says, "Well, I'll give it a try!"

Phillips-head screw

In 1936, several U.S. patents were issued for the Phillips-head screw and screwdriver to its inventor, Henry F. Phillips (Nos. 2,046,343, 2,046,837 -40). They describe a fastening system involving a shallow cruciform recess and a matching driver with a tapering tip that conveniently self-centers in the screw head. Phillips founded the Phillips Screw Company to license his patents. After three years of rejection, he finally persuaded the American Screw Company to spend $500,000 developing a manufacturing process and manufacture the screws. General Motors was convinced to use the screws on its 1936 Cadillac. By 1940 virtually every American automaker had switched to Phillips screws.
