Dumb Aussie junkies mauled by stolen koala, so they tried a croc

Gnat sez, "Aussie thieves try to steal a koala to sell for drug money. They get 'scratched to shit'. So they turn to everyone's #2 redeemable-for-speed animal, the freshwater crocodile. Convict genes will out! This story is remarkable for the persistent, diligent, hard-working stupidity of the criminals and the genial bemused zookeeper." Link (Thanks, Gnat!)
