Now it's the one where Homer finds an undeveloped roll of film in his old suit, which turns out to be exclusively photos of Bart and Lisa fighting when they were younger, sending the family on a trip down memory lane to the first time the two kids started getting along. When Bart was four and Lisa was two, they were at each other's throats constantly, to the point where it even gave Marge nightmares. To give them a little break, Flanders offers to let his grandmother watch them for a while. Homer and Marge leave them in her care but when she appears to die, Bart and Lisa head into the city on their tricycles in pursuit of a passing ice cream truck, and have to fend for themselves.
