When I was in the navy, had a friend that was the class clown. He got out of the Navy in Hawaii, working for Honolulu, teaching their maintenance guys how valves work. It is basic plumbing at best. He was making good money from that. But wait! Since he got that job and the county didn’t have anyone to teach their folks, he got paid extra to teach the county guys as well. And, well, the state had to have someone to teach their folks, so he moved right into that as extra money as well. He was making more than enough money to support himself in HI teaching stuff we all learned in year one in the navy. Guess he did good, after he stopped laughing about how quirky it all was.
