This rather wonderful story on the BBC, recounts how Tasmanian Wallabies are eating opium poppies and creating crop circles as they hop around "as high as a kite".
The story is made all the more fabulous by the assortment of comments people have left.
My favourite is probably "I have seen a stoned wallaby but I don't know about them making crop circles. The one I saw was slurring his words and asking me for a dollar as he was trying to get the boat to see his brother in New Zealand - he looked in no mood to be formulating a series of complex agricultural design patterns. I could be wrong - they might have masterminded the twin tower attacks, who really knows?".
