When Abe and two of his friends move in with the Simpsons after the Springfield Retirement Castle closes, Homer begins to embrace their lifestyle. Meanwhile, Nelson initiates Bart into the bully group after coming to his defense.
Bart sticks up for Nelson and this makes Nelson invite Bart to be a bully. Meanwhile Grandpa Abe and two of his fellows from the retirement home have moved into The Simpsons home until the irregularities of the nursing home are fixed. The bullies are out in the park and are invited to a Bully Rally Saturday night where they spoof The Warriors (1979), as Bart's slingshot is used to frame him. Now they have to make their way back to Springfield.—sscialli
