Here's an interesting item: A parrot in Massachusetts has apparently grasped the concept of zero. This is surprising because "zero" is considered to be an abstract concept that even human babies can't understand until after the toddler stage.... Heck, in some cases, some humans can't do that even after they have been President of the world's sole remaining superpower for several years.

I'm not sure about the details of the experiment, but I'm guessing the bird was asked how many WMD's were actually found in Iraq.
