50-50 partners
A very successful businessman had a meeting with his new son-in-law. "I love my daughter, and now I welcome you into the family," said the man. "To show you how much we care for you, I'm making you a 50-50 partner in my business. All you have to do is go to the factory every day and learn the operations."
The son-in-law interrupted. "I hate factories. I can't stand the noise."
"I see," replied the father-in-law. "Well then you'll work in the office and take charge of some of the operations."
"I hate office work," said the son-on-law. "I can't stand being stuck behind a desk all day."
"Wait a minute," said the father-in-law. "I just make you half- owner of a moneymaking organization, but you don't like factories and won't work in a office. What am I going to do with you?"
"Easy," said the young man. "Buy me out."

António Egas MonizDied 13 Dec 1955 at age 81 (born 29 Nov 1874).Portuguese neurologist and statesman who was the founder of modern psychosurgery. In the 1920s, he pioneered the technique of cerebral angiography, enabling X-ray examination of arteries in the brain. In the 1930s, he developed the original form of prefrontal leucotomy (lobotomy), an operation for relieving severe symptoms of psychiatric illness. The operation consisted of inserting a sharp knife into the prefrontal lobe of the brain, roughly the area above and between the eyes; it required the minimum of equipment and lasted less than five minutes. For this development, he was awarded a share of the 1949 Nobel Prize for Physiology or Medicine with Walter Hess. |
