Derek Bickerton has spent more than 30 years researching Creole languages on four continents for his book, "Bastard Tongues: A Trailblazing Linguist Finds Clues to Our Common Humanity in the World's Lowliest Languages." Bickerton gives Jim Fleming examples of various Creoles and translates them for him, and explains that Creoles were improvised languages people came up with when they had no common language and had to communicate.
