Ozzy Osbourne vs. Superfan

Broadcast in 2005, Ozzy Osbourne participated in a trivia segment formatted similarly to Jeopardy!. He competed against Robert Dwyer, the webmaster of the Black Sabbath Live Project, a fan site dedicated to the band. The quiz focused on topics related to Osbourne's music career, his tenure with Black Sabbath, and aspects of his personal life. The segment was designed for comedic effect, highlighting Osbourne's well-known eccentric personality and occasional lapses in memory, contrasted with Dwyer's extensive knowledge of Osbourne and Black Sabbath trivia.
This was aired on an episode of Jimmy Kimmel Live! broadcast in 2005.
