I've created a page with all the information currently known about the upcoming Season 18, some of which is listed below. Continuing the trend from last year, some episodes will air in September before the baseball in October. Currently two are confirmed, but there may be a third. The Season will then continue in November with the Halloween episode.
The Mook, the Chef, the Wife and her Homer (HABF15)
Lisa befriends Fat Tony's son, Michael, who wishes to be a chef rather than a mobster. During a dinner party with the Simpsons, Fat Tony is shot and the mobsters want Michael to be the new kingpin. But when he declines, Homer takes over and leads the family on a major mob spree. Metallica are reported to be guest starring in this episode (though it seems they would fit better into the next episode below).
Airing September 10, as the Season Premiere.
Jazzy And The Pussycats (HABF18)
After Bart's arm is mangled by a tiger that Lisa rescued from the local pound, Bart organizes a benefit concert to raise money for an operation to repair his drumming arm. The White Stripes guest star.
Airing September 17.
Treehouse of Horror XVII (HABF17)
Fran Drescher will guest star as the voice of "Golem." Dr. Phil McGraw and comedian Richard Lewis also guest star.
Airing November 5.
G.I. (Annoyed Grunt) (HABF21)
After Bart gets out of a commitment to join the Army at 18, Homer falls prey to a couple of Army recruiters and lands himself in basic training. Homer, of course, treats this like summer camp and infuriates his hard-nosed colonel, voiced by Kiefer Sutherland when he is unfazed by the constant hazing and humiliation.
Airing November 12.
