6. CM Punk vs. Teddy Hart
https://www.youtube.com/watch?v=IS4MVaxSps0 Teddy Hart, the supremely talented worker who never met a person he didn't piss off, had major heat with CM Punk stemming from an incident in Ring of Honor where Teddy went off the rails. Hart had previously been the youngest person ever to sign a WWE developmental deal, signing his contract at only 18 years old before being released for "attitude problems". Hart ended up in Ring of Honor and took part in a scramble cage match involving numerous other workers. After being eliminated in the match, rather than selling the moves he just took, Hart scaled the steel cage and began to perform moonsaults and shooting star presses onto other wrestlers who were not anticipating the moves at all. Hart then left the cage and threw up at ringside, claiming he suffered a concussion during the match and couldn't remember why he climbed the cage. After this, CM Punk ran into Teddy Hart before a TNA show at a restaurant called the White Trash Cafe (catchy name). Punk allegedly made a comment to Hart about his immature and dangerous behavior and, soon enough, both men were fighting outside of the restaurant. Sabu broke up the fight fairly quickly and, soon after, Punk and Hart were both gone from TNA.
