There's a village in Spain that has a yearly festival where men dressed as devils jump over babies that are lying on mattresses. There are several mattresses lined up on a street and each one has a few babies on it.
The purpose is to drive away evil andcleansethe babies of their original sin. The devils also chase teens through the streets and spank them with a whip. Again, to drive away evil.
The festival's been going on since 1620.
