For a number of years I was on the receiving end of the freight - delivered mostly to Northern Virginia & NW Wash DC. Had a delivery to the FBI building, small box about 10 inches long and 5-6 inches square. Sounded like something was loose inside as I approached the guard gate, so I check the waybill for the description...
"Human hand - crime evidence"
Gave me the creeps for the rest of the day.
Cheers, y'all.
