Some of the people that commented on that video are right, though. He shouldn't have pranked next to a busy road.
Now I'm laughing, but knowing how pathetically easy I'm to be scared irl, I'd perhaps be one of those people running and screaming in terror.
There were a few who almost got hit by a car, it was dumb to perform this prank in the middle of the street, what would he have done if one was hit? Hardly funny when people almost get hit by cars.
