This happened back in February, but it's making the rounds now. It's security video of a robber with a shotgun busting through an Idaho couple's front door, and the guy who lives there does not back down.

He starts fighting with the robber and they wrestle around until they end up rolling down the stairs and out of sight. You also hear the guy yell, "Wrong house, buster." The robber was arrested later, and no one was seriously injured.
