Kate and Andy have an unexpected visitor.

It's time for another exclusive clip from Nat Geo's "Life Below Zero," a reality series that follows a group of six hardy individuals as they make their homes and livelihoods in remote Alaska. Who can say why? I just work here.

In the clip from this week's episode (entitled "Opportunity Knocks"), watch with muted horror as a young bear is menaced by Andy's rifle while adorably investigating the couple's delicious-smelling fish rack. Run, little guy, run!

"Life Below Zero" airs Tuesday at 9pm on the National Geographic Channel.
