Roots (S13E01)

When Langley Falls plans to build an Arena Football stadium, Stan learns that the construction will require that an old tree be torn down... a tree Stan claims is his father. To save the tree, Stan must face off against Roger, who stands to make a fortune by paving the stadium’s massive parking lot. Meanwhile, when Steve is concerned that, unlike the other boys his age, he isn’t growing, he seeks out the services of an unorthodox specialist. (iTunes)
