Kukeri is a yearly Bulgarian celebration that traces its roots back to ancient Thrace. Dancers wearing goatlike costumes parade around in order to frighten evil spirits away. Like a lot of spring celebrations, it contains elements of death and rebirth, as well as fertility and bacchanalia.
In other parts of the world, spring is celebrated by eating large amounts of pastel-colored candy nestled in baskets full of plastic grass. Evil spirits are frightened away by the presence of hideous baby chickens made from synthetic marshmallow. Sugar comas usually preclude any bacchanalian pursuits. Movies featuring Charlton Heston also contribute to the general anhedonia.
