Next season's guests on "The Simpsons" will include some old faces, some new ones and a Worm. Returning for roles on the Fox cartoon will be Alec Baldwin, who appeared on the show in 2002, and Kelsey Grammer, who will reprise his role as Sideshow Bob, the network announced Thursday.
In the season opener (dubbed "Bonfire of the Manatees"), Baldwin plays Caleb Thorn, a marine biologist who attempts to steer Marge away from Homer.
Former NBA star Dennis "The Worm" Rodman and NFL quarterback-turned-broadcaster Terry Bradshaw will make cameos as themselves for the annual "ghoultide" Halloween episode.
Other guest athletes include New York Yankees pitcher Randy Johnson and boxer Joe Frazier.
Ricky Gervais, William H. Macy, Lily Tomlin, Frances McDormand, Rob Reiner and Richard Dean Anderson are all also slated to appear in episodes.
The 17th season of "The Simpsons" premieres Sept. 11 (8 p.m. ET).
