Notice the contrast of the color of the horse, to the horses' balls, on Castle Hill in Buda. For whoever saw the statue of Juliet in the city of Verona, Italy, knows that the shiny part of a statue is the one that is usually touched by endless amounts of people. While the one who touches for Juliet are by tourists, the ones to touch the balls of the horse are...students!
Every year, in May, when the students in Budapest begin finals, students come to shine the balls of the horse, as a good luck charm on their exams.
If you thought that maybe these actions are embarrassing, think again. This is a real ceremony - the Ceremony of Shining of the Balls.
