Manger-ality! Baby Jesus wins. Flawless victory.

Greek Orthodox and Armenian priests attacked each other with brooms and stones inside the Church of the Nativity as long-standing rivalries erupted in violence during holiday cleaning on Thursday.

The clean-up turned ugly after some of the Orthodox faithful stepped inside the Armenian church's section.

The basilica, built over the grotto in Bethlehem where Christians believe Jesus was born, is administered jointly by Roman Catholic, Greek Orthodox and Armenian Apostolic authorities.
