You're staggering down the street on a sunny day with a beer in hand, experiencing that glorious stage of inebriation when you feel A. completely invincible and B. like you're in a world utterly without consequences.
You spot a policemen, surrounded by a bunch of suits, giving some sort of solemn address into a TV camera.
You think of all the times you've been wronged by the rozzers - OK, not you personally, but they're all corrupt right? They're the man - and sense a glorious opportunity.
'BULLSHIT!' you shout, at the top of your voice, and stroll on, convinced they'll be too embarrassed to do anything other than ignore you, knowing you've scored a victory for the oppressed everywhere.
That's unless you're in Australia.
In Australia, the police office will stop his interview immediately, walk over and haul your smelly backside out of there for trying to make him look stupid.
That's precisely what happens in this video filmed in Albury, New South Wales and posted to Facebook by Prime 7 News Border, where it has been gleefully watched a little under half a million times at time of writing.
The moral of the story?
Never drunkenly heckle a policeman, no matter what he is doing. But then you knew that already. Didn't you?
