After Batista did his heel turn in 2009, he and Rey Mysterio Jr got in a feud. After a particularly brutal street fight, Batista ended up being the victor. But Batista wasn't done. After the match, Batista went out of the ring and got a steel chair and opened it up, leaving enough space for Rey Mysterio's knee. He climbed up the turnbuckle, and was about to jump on Rey's bad knee. But The Undertaker wasn't about to let that happen...*GONG* Cue the lights going out, they come back on, apparently Undertaker saved Mysterio and gave Batistaan ass beating to remember. The fact that Undertaker went out of his way to save little Rey is definitely a CMOH.
