What's funny about this video isn't just the fact that the mailman gets run over by his own mail truck after exiting the vehicle and leaving it in reverse.

It's that the unmanned mail truck is able to weave itself through the parking lot without causing any damage before it actually runs over the forgetful mailman. (Eventually, though, the runaway mail truck does start hitting parked cars.)

Of course, the mailman who was unceremoniously run over is fine -- or else we wouldn't be going on about how funny it all is.
