Do not mess with a mama bear trying to get her cub. Do not do it. Even if there's a cute baby bear hanging from your garage door's rails, swinging above your Audi Allroad, hoping to avoid your barking dog. Do not do it.
As you can see, mama will fill find a way to get her baby. She'll lift that garage door open so fast. Do not mess with her. Just have fun videotaping behind the safety (maybe?) of a glass door.
