A mysterious credit that appears at the end of all episodes from Season One is for "The Far Side" cartoons by Gary Larson, courtesy of Chronicle Features. It's unclear why this credit appears since there is no evidence of the cartoon's use or even a reference throughout the show. It is because in an early episode, a Larson cartoon appears on a bulletin board in a shot and the credits were not changed after that episode.
Sylvia Van Buren is credited for writing the episode "Epiphany". Two other scripts ("The Walls of Jericho" and "The Good Samaritan") are pen-named under amalgams of her name and that of Clayton Forrester. This was because thee was a writers' strike going on at the time and the writers did not want to be credited.
