Just a reminder: bears are no joke. 

Bears are on a perpetual hunt for food, and a recent video out of Lake Tahoe shows exactly how far they will go to find it. 

Security footage from a cabin near the lake shows a rather large and healthy brown bear taking out the front door like it was nothing. The bear crashes through the door—frame pieces flying—and has a look around. 

The bear took a tour of the home like he owned the place, then decided to head outside and sit by the door. Local wildlife officials were called to the scene so the bear could be relocated (hopefully).

Bear encounters are pretty common in mountainous and wooded areas. Luckily, no one was injured in this home invasion, but an Aspen, Colorado, man was not as lucky

"The incident began about 1:30 a.m. (Friday, 7/10) when a homeowner responded to noises in his house. A large bear had entered the home through the front door," Colorado Parks and Wildlife said in a statement. 

Michael Chernosky saw the bear in his kitchen and tried to lure it to the garage and away from the rest of the family in hopes it would exit. It worked at first, but, unfortunately, when he opened the garage door, the bear spooked and took a swipe at Chernosky.

"...As soon as we looked at each other, he just smacked me … and after I got out of the way and started yelling, he left," said Chernosky to Good Morning America. "Luckily, [the bear] wasn't really after me. He just looking for food, and then I don't think he was planning on encountering me either."

That one swipe sent Chernosky to surgery with severe, but not life threatening, lacerations to the cheek, jaw, and neck. 

And that's just one of the many encouters that have made the news this year. Check out this black bear who got up close and really personal with a hiker in Mexico, or this bear cub that was making its way through a Colorado neighborhood.  

“This is a good time to remind everyone who lives in bear country that they need to be vigilant and responsible,” Colorado Parks and Wildlife said. “Proper management of trash and recycling is the first step to keeping bears away from neighborhoods. Locking doors and windows and keeping cars locked is also important.” 

Also, don't take pictures or approach bears. Leave them alone. Here's a good example of why: Bear Lunges Toward Woman When She Tries to Take Pic With It. Play stupid games, win stupid prizes. 

If you happen upon a bear in the wilderness, identify yourself by speaking in a calm, appeasing tone. Back away slowly, preferably in the direction you came. Walk, don't run, and keep your eye on the bear so you can see how it will react, says bearaware.com. This works. I ran into a yearling brown bear turning a corner on a trail, and luckily, we both scared each other so much that it headed up a tree and I spoke up while backing down the trail calmly from wence I came (then freaked out and booked it back to my car once I was out of the bear's line of sight).
