Cannibals capture three men...

Cannibals capture three men. The men are told that they will be skinned and eaten and then their skin will be used to make canoes. Then they are each given a final request. The first man asks to be killed as quickly and painlessly as possible. His request is granted, and they poison him. The second man asks for paper and a pen so that he can write a farewell letter to his family. This request is granted, and after he writes his letter, they kill him saving his skin for their canoes. Now it is the third man's turn. He asks for a fork. The cannibals are confused, but it is his final request, so they give him a fork. As soon as he has the fork he begins stabbing himself all over and shouts, "To hell with your canoes!"

Cullen Whipple

Died 23 Oct 1868 at age 67 (born 4 Sep 1801).American inventor and machinist of Providence, RI, who patented the first practical screw machine in the U.S. for making pointed screws (14 Dec 1852, No. 9,477). Early screws had blunt ends, and it was necessary to drill a starter hole. In Oct 1840, he was one of ten incorporators of The New England Screw Co. He invented a machine for the company to use cutting the threads of screws (patented 18 Aug 1842), another for shaving the heads of screws (patented 6 Apr 1843) and one for removing the burs left in cutting the slots in the heads (patented 19 Apr 1843). He invented and patented seven other machines or devices for improving the manufacture of screws, such as a Screw-Blank Feeding mechanism (3 Jun 1856, No.15,052).«
