Back when I was a field engineer for a scale company, we did work for a big chemical company, and they'd make you sit through their safety video before you could do any work in the facility.
The video was hysterical. The safety officer of the plant had made it himself on the premises with like a gigantic VHS camera probably the size of a bazooka, and he was a big, goofy fatso of a guy with a ferocious combover, and he put himself and other rando plant workers into "accident scenario" recreations of like falling off ladders and getting hit by forklifts and whatnot.
Security Sam was a terrible actor, but he really threw himself into the roles with gusto and hammed it up and made cornball jokes.
The two funniest I remember were "Never take off your hard hat" that had a wrench being dropped from above and landing on his head. He punched that role up with his "dizzy eyes" rolling in his head and a ketchup packet squirted on his Trump-like combed-over mane of hair to simulate a ghastly scalp injury.
Then there was "Never turn any valves without authorization" that romp saw Sam blasted in the face with scalding steam(a fire extinguisher discharged in his face). Sam's combover flap flew straight up vertical a good foot long when they wooshed him in the face, and then, after a rough cut, Sam gets up off the ground, and they've got bright-red makeup "steam burns" slathered on his face, and Sam starts screaming in mock agony.
It was so goddamn funny we rewound it, and watched it again.
