“The Legend of Ranger Joe” is the 100th overall episode of Full House.
The episode is the sixth installment of season five and originally aired on October 22, 1991. Its overall numbering counts episodes across the series rather than restarting with each season, placing it at the show’s 100th episode milestone.
In the story, Joey Gladstone auditions to replace Ranger Roy, the retiring host of a children’s television program. Joey briefly loses the opportunity after accidentally triggering Roy’s acute physical paranoia, but he ultimately proves himself when he steps in to save the program.
The episode also includes subplots about Michelle’s tap-dance obsession and Jesse worrying about choosing names for his unborn twins. The number 100 is sometimes confused with the season episode number: it is season 5, episode 6, not the sixth overall episode.
