Parking Ticket

My wife and I went into town and visited a shop. When we came out, there was a cop writing out a parking ticket.. We went up to him and I said, "come on man, how about giving a senior citizen a break?" He ignored us and continued writing the ticket. I called him an "asshole." He glared at me and started writing another ticket for having worn-out tires. So my wife called him a "butthead".

He finished the second ticket and put it on the windshield with the first. Then he started writing more tickets.

This went on for about 20 minutes. The more we abused him, the more tickets he wrote. He finally finished, sneered at us and walked away. Just then our bus arrived, and we got on it and went home.

We always look for cars with Obama 2012 stickers. We try to have a little fun each day now that we're retired. It’s so important at our age!!

Haynes automobile

In 1894, Elwood Haynes successfully tested his one-horsepower, one-cylinder vehicle at 6 or 7 mph at Kokomo, Indiana. He was an American pioneer whose vehicle was one of the first automobiles built. Now on exhibition at the Smithsonian Institution, Washington, D.C., Hayne's vehicle is the oldest American-made automobile in existence. He manufactured automobiles 1898-1925. He was a trained engineer and chemist who discovered several alloys, including a stainless steel (discovered 1911, patented 1919). He was the first to use aluminum in an automobile engine.
