I had both of my toe nails removed in Afghanistan and other than some gauze it was pretty much an open wound. This was in 2009 when they were integrating the Afghan national army with our unit so they were staying on base with us using our facilities. One night I went to use the shower and they were all used. I waited for one to open up and there was this afghani who ran out the stall giggling. I was thinking he was a funny guy and didn't think of it. It's pretty dark in the showers so I got in and started showering. The drains were clogged so I had water about ankle deep and I was in it for a good 5 min. After I turned off the water, I opened the curtain and noticed a smell. I looked down and there was a turd floating near my feet. Needless to say, mr. Abdullah was laughing because he took a dump in the shower and I was immersed in poop water with my raw toes. Both my toes got infected and you will never understand the pain of having corpsmen scrub your raw toes for 5 minutes with no local anesthesia. To this day, my toe nails look like crap and will never use another person's shower.
First week of boot camp in 2003. Drill instructors have 70 of us in the showers, make us pile up nut to butt. Then he makes us sit down on top of each other. Most awkward feeling. I always joke to my wife that I've seen more balls than she will ever have in her lifetime.
