The Devil

George Bush, Queen Elizabeth, and Vladimir Putin all die and go to hell.
While there, they spy a red phone and ask what the phone is for. The devil tells them it is for calling back to Earth.
Putin asks to call Russia and talks for 5 minutes. When he is finished the devil informs him that the cost is a million dollars, so Putin writes him a check.
Next Queen Elizabeth calls England and talks for 30 minutes. When she is finished the devil informs her that the cost is 6 million dollars, so she writes him a check.
Finally George Bush gets his turn and talks for 4 hours. When he is finished the devil informs him that the cost is $5.00.
When Putin hears this he goes ballistic and asks the devil why Bush got to call the USA so cheaply. The devil smiles and replies: "Since Obama took over, the country has gone to hell, so it's a local call."

Elias James Corey

Born 12 Jul 1928.American organic chemist, winner of the Nobel Prize for Chemistry in 1990 "for his development of the theory and methodology of organic synthesis." He is principally known for his work is in computer-aided analyses of synthesis problems. Using "retrosynthetic analysis," a target molecule might be broken down by reversible steps into simpler, readily available compounds, which is greatly assisted by the use of computers. Corey has synthesized over 100 substances for the first time, including terpenes (plant oil hydrocarbons) and ginkolide B (an extract from the ginko tree used to control asthma.)
