A little military humor for the crew:

A newly commissioned lieutenant was talking with his company first sergeant. The LT says, "You know, Top, I've always wondered why the officer rank insignias are what they are."
The first sergeant says, "Well sir, let me break it down for you. Second lieutenants wear a gold bar to show that you're valuable, but malleable. First lieutenants wear a silver bar because they're still valuable, but less malleable. Captains have two bars because they're twice as valuable, but still kind of malleable. Colonels wear eagles because they soar over all the rest of us. And generals wear stars because they're the stars in our galaxy."
The lieutenant says, "Makes sense, Top. But what about majors and lieutenant colonels?"
"Well sir, that goes back to the Garden of Eden. Adam started it, and we've been covering our pricks with leaves ever since."
