As secure as we like to think our homes are, it's hardly impossible for some particularly enterprising critters to find their way in.
But while bug infestations are an everyday occurrence and we can occasionally find that a bird will turn our houses chaotic after finding its way inside, there are some of nature's intrusions that are much harder to explain.
Nobody ever expects to find bears in their basement or a moose in their classroom, but such things have happened and there's not really any debate as to whether we should high-tail it and call animal control when they do.
However, that's not what one Tennessee couple woke up to find one morning and while what they did discover was likely a more welcome sight, it was just as mysterious as those cases.
