#3 Big Show attacked Rey Mysterio at WWE Backlash
After WrestleMania XIX, Big Show was in a program with SmackDown's top underdog, Rey Mysterio. It all started after a tag team match between the two. As Show and A-Train celebrated their victory against Mysterio and Tajiri, Mysterio gained the upper hand by surprising Show with a 619 off-the-ring post.
This led to a humiliated Show who felt anger and fury. Show and Mysterio would have a match with each other later that month at WWE Backlash. With Show defeating Mysterio with a massive chokeslam, the WWE fans believed that Show finally got what he wanted.
Unfortunately for Mysterio, Show was just getting started. As Mysterio was being stretchered out of the ring, Show reemerged and attacked Mysterio. Big Show lifted the stretcher Mysterio was strapped to and swung it across the ring post.
This assault made Rey's head bounce on the ringside, sidelining him for almost a month.
