Funeral for a Fiend

The Simpson family agrees to go to a rib restaurant, and after arriving, they discover Sideshow Bob attempts to murder the entire family. When Bob is captured by the police, he is put on trial, where Bart throws away his vial of medicine, inadvertently killing him. Bob's brother Cecil invites Bart to pay his last respects to Sideshow Bob, which turns out to be an elaborate plot by Bob's family to have Bart killed once and for all.
