In "Battle-Dib", the show requires potential audience members to take a test, mainly covering science and Professor Membrane's personal life. After getting at least a 94.1%, one moves onto a battle arena to fight another potential audience member. After winning two out of three rounds, the winning contestant either goes in to the audience or goes on for another test before going in to the audience. The one who loses is escorted out of the building. As seen in this episode, Dib has served as an "assistant" on the show.
