Audition
Alexanderia the Great's audition consisted of jumping into a pool after her hands and legs have been shackled and 30 feet of chain have been wrapped around her body with eight padlocks. She escaped from her chains after 96 seconds. Howard Stern, Heidi Klum, Mel B, and Howie Mandel all voted "Yes," sending Alexanderia to the Vegas Round.
