One of my bio lecturers began a lecture with "The koala is a junkie and a moron," which I thought was a pretty funny thing for a very camp little middle-aged guy to say.
Goddammit this is animal cruelty. Koalas only flap their ears when they are trying to fly away, but obviously this one has been nailed to its perch. That's just plain mean. Jesus that makes me mad what kind of sick fuck would nail down a Koala
No, they definitely scratch people, but the ones they put out to be handled are the most placid/brainless/high ones. They can be quite aggressive in the 30 minutes or so a day when they're not sleeping or eating. They also piss on people pretty often.
