Summary: Something Mongo said yesterday about the choo-choo makes Bart pause. He asks Mongo if he knows why Hedley cares about the where the choo-choo is going? Mongo replies with a deeply philisophical, "Don't know. Mongo only pawn in game of life." Bart is convinced that he and Jim need to head out the railroad and do a little snooping. We transition to the site of the rail line being built. As the camera moves, Charlie comes into frame and heads to what looks like a large oak barrel.
