Robert William "Bob" Howard (born January 29, 1963) is an American semi-retired professional wrestler. He is best known for his 16-year career with the World Wrestling Federation/World Wrestling Entertainment (WWF/E) under the ring names Thurman "Sparky" Plugg, Bob "Spark Plug" Holly, Bombastic Bob and Hardcore Holly.
After debuting in 1990, Holly worked for Smoky Mountain Wrestling and other independent promotions, before joining WWE full-time in 1994. Initially portraying the character of a NASCAR driver, Thurman "Sparky" Plugg, his name was soon changed to Bob "Spark Plug" Holly, before forming a team with Bodacious Bart, known as The New Midnight Express in 1998. After becoming known simply as "Hardcore Holly" in 1999, he was joined by on-screen cousins, Crash Holly and Molly Holly. In 2002, he suffered a broken neck, which sidelined him for over a year. Upon his return, he engaged in minor feuds with wrestlers such as Mr. Kennedy and Rob Van Dam, before forming a tag team with Cody Rhodes in 2007. Holly was released from WWE in 2009, returning to the independent circuit. He published his autobiography, The Hardcore Truth: The Bob Holly Story, in 2013.
