David Daniel Nichols, the content creator behind @nbconstruction.creators, usually shares construction tips while working in attire that many professionals in the field would consider, at the very least, risky. And this time, that habit ended up costing him.

While filming an explanation of how to join two pillars with a lag bolt, Nichols focused so much on the demonstration that he failed to notice that his testicles had ended up right between the two pieces he was about to fasten.

Seconds later, as he tightened the joint, the video went from tutorial to survival scene. A scream of pain confirmed it: his testicles were being crushed, while the builder desperately tried to unscrew what he had just installed. Luckily, he managed to “free himself” without any problems. A tutorial no one will follow.
