Once, an employee who was preparing to quit hopped onto the fulfillment center's conveyor belt and rode it merrily through the entire facility.
The funniest story, however, may be from 2006 and it involves a temporary employee at a Kansas fulfillment center.
He would show up at the start of his shift and leave at the end of it, but he never logged any hours in between. It took at least a week for anyone to discover what was going on: He had tunneled out a den inside an huge pile of empty wooden pallets. Completely out of view, he had used Amazon products to make a bed, ripped pictures from Amazon books to line his make-shift walls, and stolen Amazon food to snack on. When he was discovered, he was (unsurprisingly) fired.
