There is no animal on the face of this planet that gives less of a fuck than a wombat. I went to Mt. Samaria over the weekend and while you're driving along the roads in the state forest, you see deer, wallabies, kangaroos, rabbits, foxes, possums all shitting themselves and bolting when the car goes past. Wombats just waddle their care free arses across the road right in front of your car, not giving a fuck. They seriously never break stride.
Watch this video for an example of how little fucks wombats give:
