BBC NEWS | Asia-Pacific | 'Stoned wallabies make crop circles'

Read the comments from bemused Aussies underneath the piece

Yup, definitely stoned wallabies. If that's not a message to the Supreme Outer Space Wallaby advising her of our military strengths, I'll eat my shorts.

Yeah, yesterday we had news of stoned wallabies and a monkey urinating on a president. I love odd news. I'd also love to see the faces of the crop circle advocates when they learned about this.

Whew, thank god for that! I thought they were made by mentally challenged pet rocks!
