Knife-wielding squirrel invades Canadian woman's yard

From the Toronto Sun:

"We have a lot of squirrels in our backyard," she told the Sun Friday. "I noticed he had something blue in his mouth and I did a double-take and then I realized it was a knife. I started filming."

Diamond said her first reaction was whether the squirrel was going to hurt itself.

"He was just gnawing on it, happily," she said. "Then he dropped it. And I thought, 'That was it.' But then he came back to keep gnawing on it. Maybe he was sharpening his teeth on it, I haven't seen that before."
