Homer refuses to pay an airport tax for their flight, they hop an illegal train ride and share a railroad car with a singing hobo. The hobo enchants them with tall tales taken from American folklore. He weaves stories about Paul Bunyan (Homer) saving the earth from a meteor, Connie Appleseed (Lisa) turning settlers onto the health benefits of apples, and the lesser-known adventures of Tom Sawyer (Bart) and Huck Finn.
