A group of friends went to a haunted house in Nashville when a tall figure with a skull face walked up to the friends and handed one person a knife. The skull man asked one of the women if her friend was messing around with her, she said yes and the figure handed her a knife and said well here stab him. So the girl took the knife thinking it was fake and stabbed her friend in the arm. Her friend was taken to the hospital. The group of friends thought the act was part of the show. The Thirteenth Floor Entertainment Group said that an employee was involved in the incident and they are going over safety protocol to make sure this doesn't happen again.
