The Jewish chicken-swinging atonement ritual of Kaparot can't be much fun for the chickens involved.
In fact, this one looks downright angry:
The Yom Kippur ritual involves circling a chicken three times over one's head while saying a prayer in order to transfer one's sins to the unfortunate bird, who is then slaughtered and served to the poor. In recent years it has come under fire for causing chickens unnecessary cruelty as the sacrificial poultry are often kept in poor conditions before the ceremony.
Money is a religiously-approved substitute for a live chicken, as well as a fish. No word yet on whether Angry Birds can also be used.
