Diagnosis Explained

A 90-year-old man goes for a physical and all of his tests come back normal.
The doctor says, “Larry, everything looks great. How are you doing mentally and emotionally? Are you at peace with God?”
Larry replies, “God and I are tight. He knows I have poor eyesight, so He’s fixed it so when I get up in the middle of the night to go to the bathroom, poof! The light goes on. When I’m done, poof! The light goes off.”
“Wow, that’s incredible,” the doctor says.
A little later in the day, the doctor calls Larry’s wife.
“Bonnie,” he says, “Larry is doing fine! But I had to call you because I’m in awe of his relationship with God. Is it true that he gets up during the night, and poof, the light goes on in the bathroom, and when he’s done, poof, the light goes off?”
“Oh sweet Jesus”, exclaims Bonnie. “He’s peeing in the refrigerator again!”

Pin making machine

In 1832, a pin manufacturing machine was patented by John Ireland Howe (U.S. No. 2013). During the 19th century the American pin industry concentrated in the Naugatuck River Valley because Howe (1793-1876) built a plant in Derby, Connecticut, to make pins with the machine he invented to shape pins in one operation instead of the 18 separate steps required for hand production. He turned for mechanical help to Robert Hoe (who built printing presses.) His first working model of a machine that would make pins, though imperfect, was exhibited that year at the American Institute Fair in New York, where Howe received a silver medal. He improved the machine during the winter of 1832-33. Howe also invented a machine to stick the pins in paper packets.
