1.Jeff Jarrett

Jeff Jarrett may have received the worst firing on WWE TV, as like Daniel Bryan, his firing was actually real.
The story of Double J's firing goes back to 1999, when Jarrett left the company for WCW, allegedly threatening to take the Intercontinental Title with him, unless Vince McMahon paid him a lot of money.

Whilst Jarrett has refuted the story, when WCW folded in 2001, Jarrett was not offered a job with the WWF.
Instead, in a historic RAW moment from the March 26, 2001 episode, McMahon appeared, with screens showing both WCW and WWF content, with the WCW one featuring Jarrett.
Mocking Jarrett's character of spelling his own name, McMahon publicly fired the former WCW World Champion, with Jarrett forming TNA Wrestling the following year.
In 2018 though, it seems the hatchet has been buried, as Jarrett was inducted into the WWE Hall of Fame.
