Event on Ludicrosity

You hear a distinctly odd music coming from the west. All of a sudden, ten orcs come out from behind a dune, all in line, each with his arms on the shoulders of the orc in front of him. They are dancing to the music! It is an odd spectacle, indeed. You stare at them, stunned, until they fade into the distance. By golly, that looked fun! So you and your troops march as such for the rest of the day. Many peasants stop and laugh at you.
