The son of former wrestler, "Grizzly" Smith, Jake "The Snake" Roberts made his professional wrestling debut in 1975, joined the infamous "Legion of Doom" in 1983 and repeatedly struck fear in his opponents, especially with his finishing move, the DDT. He would then place a live snake on his defeated opponent (usually it was a Burmese Python named "Damien"). Roberts also claimed that he got his nickname from Ken "The Snake" Stabler, who was quarterback for the Oakland Raiders during the 1970s. During the mid to late 80s, Roberts entered into entertaining feuds with the likes of Ricky "The Dragon" Steamboat, "Ravishing" Rick Rude and Andre the Giant (whom he defeated by disqualification at WrestleMania V in 1989). The 1999 professional wrestling documentary, Beyond the Mat, featured an unflattering portrayal of Roberts. In December 2007, Roberts reportedly entered into a rehab program.
