Other cast members of the season included Pamela Hayden (Milhouse Van Houten, among others), Tress MacNeille (Agnes Skinner, among others), Maggie Roswell (Helen Lovejoy, Maude Flanders, among others), Russi Taylor (Martin Prince), and Karl Wiedergott. Season ten also featured a large number of guest stars, including Phil Hartman in his final appearance on the show in the episode "Bart the Mother" that originally aired in September 27, 1998. Hartman was shot to death by his wife four months before the episode aired and it was dedicated to his memory. Rather than replacing Hartman with a new voice actor, the production staff retired two of his recurring characters, Troy McClure and Lionel Hutz, from the show. However, Hutz and McClure still appear in various Simpsons comics, because a voice actor is not needed.
