The hearing aid

Seems an elderly gentleman had serious hearing problems for a number of years. He went to the doctor and the doctor was able to have him fitted for a set of hearing aids that allowed the gentleman to hear 100%. The elderly gentleman went back in a month to the doctor and the doctor said, "your hearing is perfect. Your family must be really pleased that you can hear again."

To which the gentleman said, "Oh, I haven't told my family yet. I just sit around and listen to the conversations. I've changed my will three times!"

Stillson wrench

In 1876, a U.S. patent for the first practical pipe wrench - the Stillson wrench - was issued to Daniel C. Stillson of Somerville, Mass. (No. 184,993). In 1869, he had whittled a model out of wood, which he showed to his boss at the Walworth Company. He recognised the wooden pattern showed a new type of pipe wrench, superior to anything else in use at that time, and badly needed in the growing pipe industry. Stillson was instructed to test one built in steel. The test convinced the company owner that the concept was sound. Stillson obtained a patent, and offered to sell the patent for a small outright payment. Instead, the owner graciously advised Stillson accept royalties instead. Stillson thus earned far more in his lifetime.*
