The Simpsons gets off to a rollicking start in its fourth season with "Kamp Krusty," a gem notable for its suggestion that Marge and Homer make whoopee while Bart and Lisa attend summer camp. Jon Lovitz, in master thespian mode, guest-stars in "A Streetcar Named Marge." Little Miss Springfield Lisa gets the crown anyway in "Lisa the Beauty Queen," after the winner is struck by lightning. Marge puts her charm and smarts to work in the power plant in "Marge Gets a Job"; and when Mr. Burns notices, he takes a shine to her, leading to a cozy dinner for two with the vocal stylings of Tom Jones. Homer voice Dan Castellaneta won the second of his two Emmy Awards for his work on "Mr. Plow," an episode featuring guest turns by Adam West, Linda Ronstadt, and Simpsons semi-regular Phil Hartman, here as Troy McClure. Elizabeth Taylor gives voice to the littlest Simpson in "Lisa's First Word," calling out "Daddy" to Homer after he puts her to bed. Later in the season, Homer becomes the power plant's union negotiator in "Last Exit to Springfield." Selected as the all-time best Simpsons episode in a January 2003 edition of Entertainment Weekly, the plot involves Lisa's need for braces and Homer's efforts to bargain away the union's dental plan for beer. TV Guide weighed in on the season-closing "Krusty Gets Kancelled" in both its "Funniest Moments" and "Greatest Episodes" issues. It is certainly the most star-studded episode, featuring not only Taylor's second appearance but also turns by Bette Midler, Luke Perry, Barry White, Hugh Hefner, the Red Hot Chili Peppers, and television legend Johnny Carson. Speaking of talk show hosts, Conan O'Brien authored two episodes before moving on to succeed David Letterman on The Late Show: "New Kid on the Block" and "Marge vs. the Monorail," which boasts a guest voice turn by Leonard Nimoy. They're both excellent outings in a season that is easily among the venerable program's best.
