#1 Matt Hardy

In 2005, Matt Hardy was on the shelf dealing with a severe knee injury. While out injured he discovered that his long time girlfriend, Lita, had been having an affair with Edge while on the road. Upon learning this, Hardy took to the internet and began to spill dirty secrets on his blog. Hardy even famously confronted Lita on WWE Byte (a live call-in show on WWE.com). He questioned her about the affair, and accused Edge of adultery.
WWE fired Hardy due to this unprofessional behavior and the WWE received lots of fan backlash. People felt that Edge and Lita were wrong and, they should have been the ones sent home. This led to them being booed and jeered loudly on TV. Fan's began a petition to have Hardy re-hired. He was eventually hired again and went on to work and angle with Edge and Lita based around the real life affair.
