Aussie sons prank unsuspecting dad with 'honk if you're horny' sign

Their latest offering is no different - this time, they’ve stuck a ’honk if you’re horny’ sign on the back of their dad’s car before they head out on a drive.
And as fellow motorists gleefully oblige, honing and flashing their lights, his unsuspecting dad only gets more and more irate.
We would quote him, but it would be mostly starred out - in true Aussie style, the video is completely NSFW.
You’ll just have to let the grammatical error go this time - especially since the video has now gone viral. The original Facebook video has been watched almost 10 million times.
