#1 Kurt Angle vs. Jeff Jarrett
Kurt Angle and TNA founder Jeff Jarrett began feuding in the late summer in 2008. For what seemed like no reason, Jeff aided AJ Styles in a ladder match with Kurt on Impact. Jeff later revealed he had grown angry with Kurt in his absence, for not leading TNA in the right direction. The feud quickly escalated when Jarrett hit Angle with his guitar, a match that involved him, Christian Cage and Samoa Joe for the TNA World Heavyweight Championship.
The feud briefly turned into a shoot, when an irate Jarrett went off script during a segment on Impact, slamming Kurt for speaking highly of WWE and Vince McMahon and teasing a return to WWE, in an interview during a media tour for TNA. Jeff would then defeat Kurt at Bound For Glory. Kurt would later defeat Jeff in a rematch at Genesis, and the feud would continue as a part of the Main Event Mafia vs the TNA Frontline.
The real-life issues between Kurt and Jeff were brought into the storyline in late 2010. Angle came out to make his retirement speech, after his failed attempt to win the World Heavyweight Championship, but was interrupted by Jarrett, who announced that he had made a deal with Hogan and Bischoff in order to end Angle's career.
Kurt's ex-wife Karen Jarrett would soon join the feud, aiding her new real-life husband Jeff, and Jeff and Kurt would have a deep and personal feud on TNA TV for the next 6 months, 5 of which they fought on pay-per-view in some exciting and emotional performances. The incredible feud ended in June 2011 on an episode of Impact, where Kurt defeated Jeff in a Parking Lot Brawl, that forced Jeff off TNA TV for several months.
