Man Narrowly Misses Getting Hit By 4-Foot Runaway Saw Blade

This is some security cam footage of construction worker Shane Reimche entering the Quick Trip Market just moments before a 4-foot runaway circular saw blade comes flying through the parking lot and embeds itself in the side of the door. He never saw it coming, but dude was just two seconds away from a world of hurt. My enemies? They’re never more than a single second away from a world of hurt. The Doomsday Clock? It’s already past midnight, humanity is just too far up its own ass to realize it.
