It began as any other Black Friday rush, but in 2008 at a Toys R Us in Palm Desert, Calif., something went terribly wrong. Two women began throwing verbal jabs and then actual jabs in the store's electronics department.
Then the two men they were with began fighting and drew handguns. As other shoppers scrambled to safety, the men turned Toys R Us into a scene from the Old West. They chased each other down the store aisles, firing and killing each other (but no one else) during the incident [source: Mehta et al.].
