A man walked into a doctor's...

A man walked into a doctor's office and the receptionist asked him what he had. He replied, "I got shingles."
She said, "Fill out this form and supply your name, address, medical insurance number. When you're done, please take a seat."
Fifteen minutes later a nurse's aide came out and asked him what he had. He said, "I got shingles."
So she took down his height, weight, and complete medical history, then said, "Change into this gown and wait in the examining room."
A half hour later a nurse came in and asked him what he had. He said, "I got shingles."
So she gave him a blood test, a blood pressure test, an electrocardiogram, and told him to wait for the doctor.
An hour later the doctor came in and asked him what he had. He said, "Shingles."
The doctor gave him a full-cavity examination, and then said, "I just checked you out thoroughly, and I can't find shingles anywhere. " The man replied, "They're outside in the truck. Where do you want them?"

Oppenheimer

In 1954, the Atomic Energy Commission, by a vote of 4 to1 decided against reinstating Dr. J. Robert Oppenheimer's access to classified information. The Atomic Energy Act of 1946 required consideration of “the character, associations, and loyalty”of the individuals engaged in the work of the Commission. Substantial defects of character and imprudent and dangerous associations, particularly with known subversives who place the interests of foreign powers above those of the United States, were considered reasons for disqualification. The Commission regarded his associations with persons known to him to be Communists exceeded tolerable limits of prudence and self-restraint, and lasted too long to be justified as merely the intermittent and accidental revival of earlier friendships.
