This week marked the 73rd birthday of Alex Trebek who announced earlier this year that he was going to be leaving as host of the long standing television show 'Jeopardy.' It got me to thinking about who Trebek replaced as the host of the original 'Jeopardy' show. The answer to that is Art Fleming, who left the show back in 1984. Can you name replacements for other people? Check out the list.
