New Kids on the Blecch

Homer "runs" in the Springfield marathon, but when Bart crashes the end of the race an unruly mob is ready to lynch him. A passing stranger rescues him and offers Bart the opportunity to join a new boy band "Party Posse" as the bad boy. Other members of this new band include, Milhouse, Nelson and Ralph. Using NASA technology to enhance their voices they might just make it. And they will, until it is revealed that their videos and music are rigged to brainwash people into joining the Navy. Their manager goes crazy when the government cuts off his funding, but with a little help from N' Sync, the boys of Party Posse try to save the staff of "Mad Magazine" from certain destruction.
