This week on a very special Oddball History we're lowering ourselves down into the sewer to learn all about the Great Hanoi Rat Massacre, a grisly and all too true comedy of errors set in 1902 French Indochina, as well as Mao's tragically misguided (but super popular) war on sparrows and the species of toad brought to Australia as a pest control measure in the 1930s, which has been spreading across the country and terrorizing the native wildlife ever since. ALSO: Today in history, dung beetles, and the first ever Greek Myth of the Week!
