El Colacho: the Baby-Jumping Festival (Spain)
El Colacho has seen grown men leap over newborn babies in celebration of the Catholic festival of Corpus Christi since 1620. Donning scary, vaguely Elvis-like costumes and wielding whips and truncheons, the men attempt to cleanse the babies of evil. Strangely enough, leaping over them is believed to be the best way to achieve this.
