Do you want to live forever? You can do that, in a sense, by turning your name into a noun. The French doctor Joseph-Ignace Guillotin invented the guillotine. James Brudenell, the 7th Earl of Cardigan, is known for his now famous sweaters. Jules Léotard lives on in common dancewear. That's the key! You've got to become an object, immortalized forever in the dictionary. Robert Krulwich and Adam Cole explain how it works in this catchy tune.
