A brunette goes into a doctor...

A brunette goes into a doctor's office and says that her body hurts wherever she touches it. "Impossible," says the doctor. "Show me." She takes her finger, presses on her elbow, and screams in agony. She pushes her knee and screams, pushes her ankle and screams, and so it goes on; everywhere she touches makes her scream with pain.

Since 1881, he had worked to improve the micrometers then existing. His design had a vernier scale, a smaller head, a locking device and a small knob extending from the barrel to enable quick rotation while closing the initial gap to the inserted object being measured. By 1899, his micrometer was available in a one-inch size for $6.50, including a leather case. He took out many other patents for the tools he invented or improved, and established a substantial tool manufacturing business.«
