I just had a flashback of going through the MET station prior to leaving for BMTS (Basic Military Training School). About 10/15 guys in a room, lined up shoulder to shoulder, with nothing on but our tighty whiteys.
The first command was to drop'em! Then a medical person told me to turn my head left, he put his hand on me business and told me to cough. Cough again. Turn your head right and cough. Cough again.
Then, when all of us had finished with that, the next order was about face! The lights went out. Drop'em! Bend over at the waist and spread your cheeks! This while a guy with a flashlight did a visual inspection.
I wasn't even 18 yet. I can laugh now.
