Today is the 240th Navy Birthday. Of their 240 years of service, I was part of it for 20 of those years. Anyways, today they begin their 241st year of service to the American people. 241 happens to be an interesting number.

Their 241st year should be a good year.
Several people have asked me why I joined the Navy, so I always tell them the truth. I was in need of a job, some money and an education so I decided to go talk to the Army recruiters. They told me a lot about life in the army, but it sounded like a lot of work to me. So I thought I’d go see the Marine Corps recruiters. They even showed me a movie about the Marine Corps, but it looked like a lot of work and a lot of polishing. So my next stop was the Air Force recruiters. They showed me pictures of Air Force bases with golf courses, swimming pools, tennis courts, and movie theaters. As I was about to sign up I thought I should go see the Navy recruiters, even though I thought I would be back in the Air Force office soon. So I went down the hall to the Navy recruiting office. The door was locked, the lights were off, and there was a hand written sign on the door that said “Gone Fishing”. And I thought to myself, “That’s the service for me!”
