The weirdest thing I've ever seen in the military is this one dude didn't like taken showers in the open bay style showers and would wait until everybody went to sleep. One day I was coming in from the field while the other guys were already back and said to one of the other guys, "Who the f**k is here that's taking a shower at 0200 in the morning.
This guy was a crazy mofo and immediately shouted the guys name, stripped down naked, put on his gas mask and ran into the shower started doing the helicopter right next to the homophobe.
Same dude one time ordered a pizza, they came to the door to pay, and he walked up to them wearing nothing but a Cheetos bag over his junk.
He also followed behind the First Sergeant once as he was doing a bay inspection completely naked wearing nothing but a Darth Vader mask and cape.
Only time I've ever seen a First Sergeant speechless.
As for raping people with chickens and vegemite. Must be a Navy thing.
