“Baby jumping (El Colacho) is a traditional Spanish practice dating back to 1620 that takes place annually to celebrate the Catholic feast of Corpus Christi in the village of Castrillo de Murcia near Burgos. During the act – known as El Salto del Colacho (the devil's jump) or simply El Colacho – men dressed as the Devil (known as the Colacho) jump over babies born during the previous twelve months of the year who lie on mattresses in the street. ... The festival has been rated as one of the most dangerous in the world”. – Wikipedia
