Jeff Jarrett

Context: In April, WCW was "rebooted" by Eric Bischoff and Vince Russo, with all titles vacated as a result. Bischoff and Russo also created The New Blood, a stable of younger wrestlers who feuded with the Millionaire's Club, made up of the older members of the WCW roster. Jarrett joined The New Blood, and at Spring Stampede on April 16, he defeated Millionaires Club member Diamond Dallas Page to win the vacant WCW World Heavyweight Championship. Page regained the title on April 24, and on April 25, the title was contested in a tag team match pitting Jarrett and Bischoff against Page and actor David Arquette. Arquette won the WCW World Heavyweight Championship after pinning Bischoff. Jarrett hit Page with the championship belt while special referee Kimberly Page's back was turned; WCW official Mickie Jay counted Bischoff out while Jarrett had Page pinned, who kicked out. At Slamboree on May 7, Jarrett defeated Page and Arquette in a three way triple cage match to win his second WCW World Heavyweight Championship after Arquette turned on Page.  In May, Jarrett won and lost the WCW World Heavyweight Championship on two further occasions, regaining the title from Ric Flair both times. Jarrett feuded with Nash and Hulk Hogan throughout June 2000, and on July 9 at Bash at the Beach, he faced Hogan with the world championship on the line; the match ended swiftly after Jarrett immediately laid down, allowing Hogan to rest a boot on his chest and win the title, with Hogan commenting, "That's why this company is in the damn shape it's in--because of bullshit like this!". Vince Russo subsequently came to the ring and delivered a profanity-laced interview in which he accused Hogan of politicking and claimed that Hogan had used his creative control to refuse to lose to Jarrett. Russo then stated that, while Hogan was free to keep the title belt he had just won (the "Hulk Hogan Memorial Belt"), Jarrett would wrestle Booker T for the official WCW World Heavyweight Championship later that night. Booker T won the resultant match and Hogan did not appear in WCW again. It is disputed whether the situation was a shoot, a work, or some combination of the two.  In the following months, Jarrett briefly feuded with Booker T, Mike Awesome, Sting, Buff Bagwell, and Flair. In late 2000, he joined forces with the Harris Brothers once more, with the trio defeating The Filthy Animals at Starrcade on December 17. In the same evening, Jarrett aligned himself with WCW World Heavyweight Champion Scott Steiner by helping Steiner defeat Sid Vicious.  In 2001, Jarrett and Steiner became members of The Magnificent Seven, a large stable headed by Flair. Flair and Jarrett feuded with Dusty and Dustin Rhodes until March, when WCW was purchased by the WWF.  Uninterested in Jarrett, the WWF neglected to acquire his contract, leaving him without a job. On the March 26 episode of the WWF's Raw program (which coincided with the final episode of Nitro), company owner Vince McMahon was seen watching Jarrett within the WCW venue on a television set. McMahon announced Jarrett's real-life firing on air, mocking his trademark taunt of distinctly spelling out his name by saying that he would now be known as "Capital G, Double-O, Double-N, Double-E - GOONNEE!"
