Hamburger

A man walks into a hamburger shop and orders a regular meal. Later, the waitress brings his meal to him. He takes a bite out of it, and notices there's a small hair in the hamburger. He begins yelling frantically at the waitress, "Waitress, there's a hair in my hamburger! I demand to see what is going on!"
So, the waitress takes him back where the cook is and to his demise, he sees the cook take the meat patty and flatten it under his arm pit. He says, "That's disgusting!"
Then the waitress says, "You think that's disgusting you should see him make donuts."

Edward Goodrich Acheson

Died 6 Jul 1931 at age 75 (born 9 Mar 1856).American inventor who discovered the abrasive carborundum, the second hardest substance (next to diamonds) and later perfected a method for making graphite. In his early career, he had worked at Thomas Edison's Menlo Park (1880-84), but left to become an independent inventor. In 1891, he was experimenting with an electric furnace, trying to make diamonds from a molten mixture of powdered coke and clay. Instead of diamonds, he found he had made small, gritty, hard crystals almost as hard as diamonds. He determined that this crystalline substance was silicon carbide. It was very effective as an abrasive, which Acheson patented(28 Feb 1892) and called “carborundum.” Heestablished the Carborundum Company (1894), to make grinding wheels, whet stones, and powdered abrasives.«
