This episode finds Trules chugging up the Mighty Mekong River, on a flat-top, tin-roof, diesel-puffing dinosaur, from northern Thailand to southern Laos, metaphorically and musically searching for mad Mr. Kurtz, from Joseph Conrad's "Heart of Darkness", and of course, more recently adapted by Francis Ford Coppola into his film, "Apocalypse Now", where Kurtz is notoriously played by mad Marlon Brando.
