Pretty normal

A woman went to see her psychiatrist. "I'm really concerned," she said. "The other day I found my daughter and the little boy next door together, naked, examining each other's bodies and giggling."

The psychiatrist smiled. "That's nothing to worry about, it's pretty normal."

"Well, I don't know," said the woman, "It worries me. It worries my daughter's husband too."

Herbert Osborne Yardley

Died 7 Aug 1958 at age 69 (born 13 Apr 1889).American cryptographer who organized and directed the U.S. government's first formal code-breaking efforts during and after World War I. He began his career as a code clerk in the State Department. During WW I, he served as a cryptologic officer with the American Expeditionary Forces in France during WWI. In the 1920s, when he was chief of MI-8, the first U.S. peacetime cryptanalytic organization, he and a team of cryptanalysts exploited nearly two dozen foreign diplomatic cipher systems. MI-8 was disbanded in 1929 when the State Department withdrew funding. Jobless, Yardley caused a sensation in 1931 by publishing his memoirs of MI-8, The American Black Chamber, which caused new security laws to be enacted.
