Some kids never grow up – which can be rather unfortunate for others if they happen to reach the age when the law allows them to operate machines like an automobile.

That said, enter the very loud and annoying (for anyone outside their cars) world of the train-horn pranksters featured on the YouTube channel “tdwpplaya”.

For the past three years (judging by the first clip of the sort on their channel), these adolescent-minded youngsters dressed in adult skins have been scaring pedestrians and at times, even workers and animals as well, with their train-spec horns fitted on regular passenger vehicles.

So, what do you think – are they just harmless mischief-makers or evil noise-terrorists who need to grow up?
