A case in point is the adoption of bumper stickers with "Kangaroos, run the buggers over" written on them by a rental caravan company. This is dry wit and harmless fun. If you do try to run them down you will be arrested. Even the RSPCA protested. It would be expected that the Australian Society for Kangaroos would have something to say.
The company did remove the stickers, though they should have left them because even bad advertising sells.
