What games did you play with the new LT?

Me and my buddies would go to salute a butter bar then cock our heads in confusion. He'd certainly be confused and ask what's up, to which we'd say "Sir, I think your ranks upside down". Pretty much every LT fell for it.

I was a brand new Ensign, our ship was being built in the yards. My guys made up a discrepancy that needed to be checked out, in this case a faulty lube oil tank level sensor, that needed to be checked before we could fill with oil. The access to the tank is through a small manhole cover that is in the bottom level of the engine room. The sensor is on the other side of the tank on the other side of the engine room (the tanks span the width of the ship). So, they told me I had to take a flashlight, crawl all the across and check out the sensor (as only an officer could sign off on it). As I got halfway across, the light from the manhole went out as the closed the tank on me ! I fooled them, I went and actually checked the sensor, made my way back to the manhole cover and took a nap until they opened it back up. I crawled out, yawned, and slapped the paperwork at their chest and told them the sensor was operating correctly. Then I walked off and grabbed a cup of coffee. They thought, for sure I was going to be pissed. I wasn't, I got a nap in the middle of the workday!

We left cherries on his desk or in front of his office door. Some took it well and some not so well.
