The New Ensign
The new Ensign was assigned to subs, where he'd dreamed of working since a young boy. He was trying to impress the Master Chief with his expertise learned in Sub School. The Master Chief cut him off quickly and said, "Listen, 'sir', it's real simple. Add the number of times we dive to the number of times we surface. Divide that number by two. If the result doesn't come out even, don't open the hatch."
A man joins the Russian Navy and is immediately deployed to a ship in the Black Sea. The captain is showing the new recruit around the ship, when the recruit asks the captain what the Russian sailors do to satisfy their urges when they're at sea for so long. "Let me show you," says the captain.
He takes the recruit down to the rear of the ship where there's a old Vodka barrel with a hole in it. "This'll be the best sex you'll ever have. Go ahead and try it, and I'll give you some privacy."
The recruit doesn't quite believe it, but he decides to try it anyway. After he finishes up, the captain returns. "Damn! That was the best sex I've ever had! I want to do it every day!" "Fine. You can do it every day except for Thursday." "Why not Thursday?" "That's your day in the barrel."
One reason the Services have trouble operating jointly is that they don't speak the same language. For example, if you told Navy personnel to "secure a building," they would turn off the lights and lock the doors. Army personnel would occupy the building so no one could enter. Marines would assault the building, capture it, and defend it with suppressive fire and close combat. The Air Force, on the other hand, would take out a three-year lease with an option to buy.
Having passed the enlistment physical, Jon was asked by the doctor, "Why do you want to join the Navy, son?" "My father said it'd be a good idea, sir." "Oh? And what does your father do?" "He's in the Army, sir."
"What kind of job do you do?" a lady passenger asked the man sitting next to her on the airplane. "I'm a naval surgeon," he replied. "Goodness!" said the lady, "How you doctors specialize these days!"
