Okay, you can't make this stuff up.

"Mounties raiding a marijuana-growing site recently in British Columbia stumbled upon some unexpected and burly security guards: 10 black bears."

"They weren't aggressive. They're wandering all throughout the grow-op area," said Sgt. Fred Mansveld.

"One of them hopped on the hood of the police car and sat there."

Fortunately, no-one unholstered their Doritos. Or it could have gotten ugly.
