In the video, it looks like the sidewalk is flooded which would be why this kid is trying to scale his way across a fence. His other option seems to be walking in the street and we all know that that's not exactly safe.
Unfortunately for this little fella the water is out in the street as well and his plan goes South pretty quick as soon as a car drives by and soaks him.
In the end the kid ends up not only getting his feet wet but also his back, legs, head. Pretty much he's just drenched. Oh and just to be clear here - the driver of this car is a touch on the d-bag side.
Try not to laugh at this kids expense but if you do, just know that I'm not judging you.
