An embodiment of this is the road signs. There are some good intentional pisstakes, like this one from the south west coast of Victoria, spotted a couple of years ago:
Then there are the ones that I'd love to think are intentional, but somehow reckon just weren't really thought out...

A common tactic is to use road signs to get you to stop and buy a coffee in out of the way towns ... but sometimes they employ some wit to get you to pull over (not sure what's so wrong with Galahs by the way):
They can get be a bit stern about it, too:
They can't think up their own names, though - lots of settlements are named after places in The Old Country.
They're all budding Cub Scouts, really - Be Prepared and all that (sorry for reposting this one):
