We love a good prank compilation video, and this is one of the best we've seen recently.
If you've ever sat on the front desk of a building, you'll know how mind-numbingly boring it can get. Dealing with the public, answering phones all day and a steady stream of delivery drivers with parcels.
So it's little wonder that this Irish guy took it upon himself to make his own fun.
He told each driver/courier that the handbrake of their van was down, and, well... their reactions are worth watching over and over again.
It's not known who the prankster is (get in touch if you know!), but it's already gone viral with almost 100k views in less than a day.
