A random bonfire
Sometimes, the weirdest thing a mailman can see while doing his route isn’t naked people, killer squirrels, or live tarantulas. This guy was minding his own business when a fire broke out in the middle of the road. He was the only one to witness this incredibly rare case of spontaneous combustion.
There might’ve been oil on the road, but what sparked the flames? As far as we know, this mailman didn’t have any matches on him, so he had no way of randomly tossing lit matches everywhere. That must’ve been a really amazing sight, especially since it raises so many questions.
