Phil Hartman's 2nd and final time hosting Saturday Night Live (1975). It also happened to be the very last time Hartman made an appearance of any kind on the show before his death in May of 1998.
Rodney Dangerfield appeared as himself and as a special guest on "Weekend Update with Norm MacDonald". It marked the first time Dangerfield had appeared on Saturday Night Live (1975) in over 16 years, and the very last time he ever appeared on the show.
