A business owner installed a motion-triggered sprinkler to soak people when they leave their cars blocking his driveway.
Hilarious footage shows motorists pulling into the space, climbing out of their cars, and getting a full hosing down.
Bruce Kerr and his employees need access to the driveway to get to and from his IT firm in Rockhampton, north of Brisbane, Australia.

He realised he needed to take more drastic action after drivers repeatedly ignored the “no parking” signs he had posted.
As well as installing the sprinkler, he put up a CCTV camera to film and shame the nuisance parkers.
The trick seems to have paid off.
Before, around 20 people parked in the spot every day, and many of them visited the nearby shop.
That number has now dropped to two or three.
Kerr shares clips of the drenchings on his social media page Rockhampton Chaos.
Some have been watched millions of times.
He told local media: “It has definitely deterred repeat offenders.”
Kerr, who’s in his fifties, designed and built the spray system himself, as reported by What’s The Jam.
He told local media: “I’ve got a good knowledge of plumbing systems, so I put a lot of work into the design.”
The Queensland man said: “It was ridiculous, we had no choice.”
