Kaparot.

An ultra-Orthodox Jewish man swings a chicken, later to be slaughtered as part of the Kaparot ritual in which it is believed that one transfers one's sins from the past year into the chicken, in Mea Shearim religious neighborhood in Jerusalem, September 14, 2010. The ritual is performed before the Day of Atonement, Yom Kippur, the holiest day in the Jewish year which starts at sundown Sunday. Photo by Olivier Fitoussi..
