Sunday's season opener (8 p.m. EDT) revolves around Homer's brush with mob life and includes Joe Mantegna as Springfield's big boss Fat Tony and Michael Imperioli and Joe Pantoliano of "The Sopranos."
In a September 17 episode with the White Stripes rock band, Bart is injured by a tiger that Lisa rescued and organizes a benefit concert to help pay for an operation on his drumming arm.
The landmark 400th half-hour, due to air next May, is a spoof of Fox's "24" that's titled "24 Minutes" and features the drama's Kiefer Sutherland and Mary Lynn Rajskub as their characters.
