My first job was working in an...

My first job was working in an orange juice factory, but I got canned. I couldn't concentrate. Then I worked in the woods as a lumberjack, but I just couldn't hack it, so they gave me the axe. After that, I tried to be a tailor, but I just wasn't suited for it - mainly because it was a sew-sew job. Next, I tried working in a muffler factory, but that was too exhausting. Then, I tried to be a chef - figured it would add a little spice to my life, but I just didn't have the thyme. I attempted to be a deli worker, but any way I sliced it I couldn't cut the mustard. My best job was a musician, but eventually I found I wasn't noteworthy. I studied a long time to become a doctor, but I didn't have any patience. Next, was a job in a shoe factory. I tried but I just didn't fit in. I became a professional fisherman, but discovered that I couldn't live on my net income. I managed to get a good job working for a pool maintenance company, but the work was just too draining. So then I got a job in a workout center, but they said I wasn't fit for the job. After many years of trying to find steady work, I finally got a job as a historian - until I realized there was no future in it. My last job was working in Starbucks, but I had to quit because it was always the same old grind. So, I tried retirement and found that I'm perfect for the job!

U.S.S. Nautilus, first nuclear submarine commissioned

In 1954, the world’s first nuclear submarine, the USS Nautilus, was commissioned at Groton, Conn. Its nuclear reactor eliminated diesel engines which previously limited a sub’s range and speed. Nuclear power also eliminated diesel fuel storage spaces and periodic surfacing to recharge batteries. Nautilus was launched 21 Jan 1954, and could dive longer, faster, and deeper than any submarine before it. It was 319-ft long, 27-ft beam (hull diameter), could dive to 700-ft, travel at over 20 knots, and was crewed by 11 officers and 105 enlisted men. Nautilus continued to break records in 1958 as the first vessel to travel under the Arctic ice and cross the North Pole. Decommissioned in 1980, the sub was converted into a museum in 1985. K-19, the first Soviet nuclear submarine, was commissioned 30 Apr 1960.
