Yeah, prop wash, shore line, keys to Davy Jones locker, wrap em up in tin foil on the foc'sle (for all to see) to calibrate the radar, etc. . .In the USAF it was sending an airman out for a bucket of prop wash, or 20 yards of flight line. We had an Airman come back with some of the rope from a restricted area (it's red) we hid that really quick.
Pretty sure it's called "Hazing" now.
