Talk about a dumb prank gone wrong! Are you a fast food fan? Well, if you're in Columbus, Mississippi you may want to pay close attention. An 18-year-old girl was arrested for allegedly smearing her saliva and menstrual blood on patrons' burgers. According to WCBI, Sky Juliett Samuel has been jailed in Lowdnes County Adult Detention Center for contaminating customer's food at Jack's restaurant. On Jan. 7, a co-worker witnessed Samuel in the act and later told her mother that she was handing the grossly tainted meals to customers through the drive-through window. If convicted, she could face up to five years in prison.
