It just puts 4 copies of an NPC named Steve on a road above Falkreath. When you talk to Steve you can start some small talk about the weather. Steve will then, with the literal roar of a bear, challenge you to a fight. As an unintended side-effect, every NPC now has the exact same dialogue option as Steve. Uh, have fun?

This is my first mod (sortof) I just messed around in the creation kit for a few minutes and this is the result. You probably don't want to download this if you can't remove it. It will probably fuck up your game, I honestly don't know.
