### Special Delivery

It was mailman George's last day on the job after 35 years of delivering the mail through all kinds of weather. When he arrived at the first house on his route, the whole family came out, roundly congratulated him, and sent him on his way with a tidy gift envelope.
At the second house they presented him with a box of fine cigars. The folks at the third house handed him a selection of terrific fishing lures.
At the next house, he was met at the door by a strikingly beautiful woman in a revealing negligee. She took him by the hand, and led him up the stairs to the bedroom where she blew his mind with the most passionate love he had ever experienced.
When he'd had enough, they went downstairs, where she fixed him a giant breakfast: eggs, potatoes, ham, sausage, blueberry waffles and fresh-squeezed orange juice. When he was truly satisfied, she poured him a cup of steaming coffee. As she was pouring, he noticed a dollar bill sticking out from under the cup's bottom edge.
"All this is just too wonderful for words," he said, "but what's the dollar for?"
"Well," she said, "last night, I told my husband that today would be your last day, and that I wanted to do something special for you. I asked him what to give you. He said, 'Screw him. Give him a dollar.'"
"Breakfast was my idea."

### Rudolf Diesel

Died 29 Sep 1913 at age 55 (born 18 Mar 1858).Rudolf Christian Karl Diesel was a German engineer who invented the internal-combustion engine that bears his name. After studying the four-stroke internal combustion engines developed by Nikolaus Otto, Diesel conceived of an engine that would approach the thermodynamic limit established by Sadi Carnot in 1824. If the fuel in a cylinder could be expanded at constant pressure, it could get closer to Carnot's limit. He patented the concept in 1892, while working at the firm of the refrigeration engineer Carl von Linde in Berlin. After boarding an English Channel steamer, he was found dead in the sea. It was most likely suicide resulting from depression, after having lost control over his invention and after receiving a great deal of criticism in the German engineering journals for his theories.[EB gives date of death 29 Sep 1913. Diesel's unwitnessed presumed suicide at sea leaves the exact date of death uncertain, and some sources give 30 Sep 1913, by which time he was known to be missing from those on board the steamer.]
