A hunter was rushed into the emergency room with a bear trap clamped onto his testicles. As the horrified doctor was examining him, he said "Man, how did this happen?"
The hunter explains that he was out in the woods and felt the call of nature. Bending down by a tree, the bear trap was triggered and snapped shut on his testicles. "Oh," exclaims the doctor, "The pain must have been excruciating!"
"It was," said the hunter. "The second worst pain in my life."
"Second worst? What could have been worse than that?"
"Coming to the end of the chain" said the hunter.

Railroad car coupler

In 1897, a U.S. patent was issued to black American inventor, Andrew Jackson Beard for his invention of the "Jenny coupler," (U.S. No. 594,059). It does the dangerous job of hooking railroad cars together by simply allowing them to bump into each other, when "horizontal jaws engage each other to connect the cars." Beard's idea has probably saved countless lives and limbs. It remains in use today. He received $50,000 for the patent rights to the "Jenny Coupler." Beard was born a slave on a plantation in Alabama, shortly before slavery ended. He was a farmer, carpenter, blacksmith, a railroad worker, a businessman and finally an inventor. Beard's other patents included a steam driven rotary engine, and a double plow.
