At the Over The Limit WWE pay-per-view on May 23rd 2010, the Viper Randy Orton faced his former tag team partner the Rated R Superstar Edge in a grudge match on the lower end of the card. The match had very reaction because the crowd had no idea who the two of them were supposed to be. Orton was coming off a feud with Kofi Kingston (of all people) followed by a feud with his former stablemates in the Legacy that had apparently turned him babyface without changing any aspects of his unstable Viper character: meanwhile, Edge had just turned heel at the end of April with little explanation, after returning from injury as a triumphantly vengeful babyface only three months earlier to win the Royal Rumble, and he would go on to turn babyface again at the beginning of October, again with little explanation. With no heat to speak of, in order for the match to work the two superior workers would have to pull off something special. Sadly, that wasnt to be. With the match finally beginning to get some traction with the live crowd, the Viper began to fire up over a fallen Rated R Superstar, pounding the mat from a kneeling position to signal for the RKO and then he stopped and clutched his right arm, abandoning the spot completely. The referee threw the X symbol to the back, and Edge and Orton improvised a double count out finish. Orton, a sufferer from hypermobility in the shoulders that allowed for fantastic flexibility at the cost of stability, had injured his right shoulder slightly at a house show a few days earlier, and managed to put out the joint while hyping up the crowd for his own finishing move. Thats right. Randy Orton dislocated his own shoulder while taunting his opponent. Check out the video above from around 2:25 for the abortive finishing sequence.
