Ever hear of the bears who got fed up and turned to a life of crime? What about the possum who faked his own death? Us neither, but you can find out all about it on 'Nature's Weirdest Events' tonight. Chris Packham goes all around the world in this series, investigating some of the mad shenanigans animals get up to. It's not all just hanging around in fields/forests with their feet up you know? Fans of Alfred Hitchcock's 'The Birds' might like this too, as Chris investigates crows displaying an unexpected level of intelligence. Always knew they were up to something...
