Wombat combat

[ZenGum]

I saw this line:

BigV and I fight like wombats

In UG's serious post about rememberance day, and I wondered, do wombats actually fight? I've never heard of it. Any help, Ducks? Aliantha (or Mr Antha?)
I'm an outdoorsy Aussie, and I've seen wombats active around dusk when (I'm) coming back from hikes. It was early morning for them, but they never seemed even remotely combative. Docile, rather.

It got me thinking about a new thread: strange animal fights.

Kangaroos definitely fight; theres a great video here (with cameo appearances by Mad Max in a golf cart and the worlds 3rd wost golfer).

It's not easy to fight when you're most notable feature is your super-long neck, but giraffes make good use of them here. LOL at this.

Koalas are notoriously grouchy buggers too.

So what other animals fight in a comic or amusing manner? Please, nothing that has been set up by humans, no dogfights or cockfights. Just natural, preferably non-lethal, humorously clumsy argy-bargy.

And do wombats fight?
