I was at New Scientist a few minutes ago reading this article about animals using drugs which said the following:
"The marsupials of Tasmania have found a means of passing the time on Australia's island state that could also explain mysterious local crop circles. Wallabies have been munching the poppies grown for opium by the pharmaceutical industry.
"We have a problem with wallabies entering poppy fields, getting as high as a kite and going around in circles," the attorney general was quoted in The Mercury newspaper."
Which somehow lead to me being on YouTube and running across the funniest man I've ever seen talking about how dangerous Australia is because of it's wildlife, as seen below.
