When the construction worker Isidro Mejia was recently rushed to an L.A. hospital, doctors didn’t expect him to live. His nailgun had accidentally gone off and embedded four nails in his skull and one in his spinal column. It took doctors five days to fully extract all the steel from his head.

And how, might you ask, did this poor guy wind up in this state? As the BBC reports:

“His colleagues said Isidro was using a nailgun that has both manual and fully automatic settings,” said deputy sheriff Dan McPherson.

They make fully automatic nail guns? Good grief. Why not just outfit construction workers with AK-47s? Interestingly, a Google search for “automatic nail gun” mostly turns up pages that describe nail-gun fighting techniques in first-person shooter video games, as well as stories from The Journal of Light Construction discussing the troublesome industry regulations that are preventing nail-gun manufacturers from developing, you know, nuclear powered home-improvement weapons. Er, tools.
