I used to drive those electric forklifts. Stuff like this was a daily occurrence. Especially near the end of an 18hr day.

Seriously though, we had so many accidents it wasn't funny. Ok, some of them were. One guy had to go to the hospital because he somehow got stabbed with a pencil. It went deep into the muscle, and the lead broke off inside. Another guy drove the truck right off a dock, the semi-trailer he was loading wasn't blocked, so it slid when he flew into it (We used to drive like 500MPH on these things! hehe)...another guy bumped into an set of stacked boxes and dumped 4 tons of plastic beads (used for injection molded auto parts) on him and his lift, completely burying both. We had to shovel him out.
My favorite prank to pull was to put a LARGE empty box (w/ lid) on a pallet, place the pallet in the middle of an aisle in the back of the warehouse, essentially blocking passage, crawl inside, close the lid and wait. Someone would eventually come down the aisle and need to move the pallet/box. They'd lift the pallet on the forks a bit and start driving down the aisle. After about 10-20 seconds I'd burst the lid off the box and scream, standing right in front of the guy as he's driving. It always scared the living sh!t out of whoever it was, since after working with these boxes all day, you NEVER expect them to friggin' attack you.
There was also an industrial-sized, motorized, spinning stretch wrapper, for wrapping boxes onto pallets. These boxes were huge, they held each 2-tons of plastic and were about the size of a small car. Anyhow, you'd wait for a guy to climb up on the deck and start tying the wrap to the base of the pallet. If he was standing in the right place (or wrong place, for him)...you could ambush him and start the machine, where he'd end up sealed against the box. We'd leave him there for a good 10-15mins., as long as he could breath ok.

Good times!
I didn't last long at that job.
Great video though, brought back a LOT of memories!
