Koji Kitao Versus The System
Former sumo wrestler Koji Kitao entered WWE in an effort to popularize wrestling in Japan. He was put up against Earthquake, a former sumo wrestler himself. Kitao felt ashamed since his rank in sumo was higher. When it started, he went off-the-cuff and they circled each other. Kitao kicked the ref, grabbed the mic, and announced that wrestling is fake. After this, he walked out and did not ever return.
Nailz Versus Vince McMahon
Prior to the 1992 SummerSlam, Nailz thought that he was getting paid too little for it. He confronted his boss on live television! He forced his way into the office and began to choke Vince McMahon. After he was pulled away, Nailz got fired on the spot. Years later, he tried to settle it in court. McMahon had been on trial for steroid use, and Nails served as a witness. He was still so angry that he was unable to string coherent thoughts. In the end, his terrible testimony only helped McMahon get an acquittal.
