During WWII my uncle (actually all my uncles) was in the Navy. One of them survived Pearl Harbor and spent the rest of the War sailing back and forth across the Pacific.
When he wrote home, my grandmother would gather the remainder of the family together and read us the letter. In one of his letters he asked "Is Betty Lyn still engaged to Philip?" Since I was 5 years old at the time, everybody was really puzzled. My gruff grandfather said, "Stupid women. He's telling us that he's heading toward the Philipines. Can't you figure out anything?"
Sure enough, after the War was over, we found out that his ship had been assigned to evacuate the gold out of the Philipine Treasury and transport it to Seattle for safekeeping.
That’s a good one. There’s a rumor that comes out of the military e-mails that if a soldier writes “Nothing much. Latrine duty at 1300 (or insert time)”, that means he’s ordered to be on obama’s security detail if he ever visits a military base. ;)
