A short video filmed at a border crossing in Montenegro has spread fast on social media. The clip shows a police officer singing while he went through a driver's documents. It runs for roughly fifteen seconds and was recorded from inside a car stopped in front of a border control booth. Rather than the usual stony-faced routine, the officer appears to be in a good mood, singing as he checks the papers. That small human moment was enough to turn a routine stop into viewing material online. Border crossings rarely produce anything people want to watch twice, so the clip's popularity makes sense. For once, a police checkpoint gave the internet something lighter than the usual travel complaints.
