HAHAHAHAHA! That's the second out loud laugh I've had today! That's funny, not underestimating dogs with mange!

But the real joke is that you think I can't take out a kangaroo in solo hand to hand combat. I'm not talking the biggest ones, like maybe a smaller one, like a female or a youngling, but let's say if I'd be about the same weight class.

I'd move in so fast in and under and start grappling, ju jitsu it on the ground likely with a leg sweep and a throw, then move my way into a rear naked chokehold, just choke the sucker out.

I also think I can outrun a Komodo Dragon with a piece of raw meat strapped to me on a 5 meter length rope. I can outrun it without the rope, but for insurance reasons I'd rather not.

I am also (kind of) joking and only mean all of it in good humor. :)

Edit: Although... Getting into a kicking session could maybe kind of work. Kangs got range, of course, but let it come at me with one of those tail-standing-leg kicks and me countering with a mofunking low kick to its shins or the quads and see how it feels after that. I also think they might get tired quickly doing that shit, although they're wild animals so I'm not so sure.

Edit again: Also, don't forget that humans can also bite and gouge out eyes and headbutt and kick em in the groin, every groin equipped animal underestimates the kick to the groin.

Edit once more: Of course most importantly, humans can also love, and everyone underestimates the power of love.
