As usual, the 1999-2000 season--1977-1978 in the show's chronology--was graced by a number of 1970s vets. "Red's Last Day" has singer Paul Anka and Lyle Waggoner (Wonder Woman), "Halloween" has Marion Ross (Happy Days)," "The First Time" has Maud Adams (The Man With the Golden Gun), and "Holy Crap" has singer/actor Mac Davis (North Dallas Forty). Then there's Tommy Chong (Up in Smoke), who became a frequent guest, as Fotohut owner Leo, in five of the 26 episodes and would return for several more seasons. Yet another notable episode, "Afterglow," features a Scooby-Doo-styled animated sequence.

By the end of the year, Eric (Topher Grace) and Donna (Laura Prepon) will have taken their relationship to the next level, Jackie (Mila Kunis) and Kelso (Ashton Kutcher) will have broken up, and Red will have gotten a job at the Pricemart--where he supervises Eric. The second season will end with a cliffhanger ("Moon Over Point Place") when Hyde is arrested (for something he didn’t actually do). The "sticky" situation will be resolved in the first episode of season three ("Reefer Madness"). --Kathleen C. Fennessy
