For me it's an intriguing contest with many variables at play. There is HTH's obvious weight and size advantage to consider, but on the flip side the Koala bear really has all the advantages intellectually. I think that it is quite possible that the Koala would lull HTH into a false sense of calm by holding up a Union Jack flag in one hand and a union Jack in the other saying "I think Hatton was beating Floyd after 6 rounds too, cutie!". HTH would get a big grin on his face before being kicked aggressively in the balls.

TKO round 1 to the Koala bear.
