4. Johnny Carson joined the Navy when he was 17

Johnny Carson joined the US Navy in 1943, aged 17. He wanted to become a pilot, but the Navy had other ideas. After completing the Navy College Training Program, he was commissioned an ensign in 1945, and then sent to the Pacific Theater, where he was assigned to the battleship USS Pennsylvania as a communications officer. Carson also took up amateur boxing while in the Navy, and ran up a 10-0 record, with most of the matches taking place aboard the Pennsylvania.
