Bart’s treehouse gets condemned when the Simpson backyard tree develops stump rot, and it’s up to Bart and Milhouse to stand in the way of the bulldozers until someone can find a way to save the tree. Then, Bart and Marge have a standoff over Bart’s television privileges, and Bart will go to extremely smelly lengths to win. And imagine what it would be like if Maggie were the mayor of Springfield.
