 He made a guest appearance on Nickelodeon's children's sketch comedy show "All That", doing a sketch alongside future "SNL" cast member Kenan Thompson.The appearance proceeded without incident, but the stunt comedy Farley was famous for was minimal, arguably because it was noticeable Farley was wheezing heavily and straining himself to perform.On October 25, 1997, Farley made his final appearance on "Saturday Night Live", the only time he hosted the show.
