"The origins of chocolate, which is derived from the Theobroma cacao tree, stretch back at least 4000 years.The plant is believed to have originated in the Amazon or Orinoco basins in South America and was regarded by the Aztecs as being of divine origin ('Theobroma' means 'food of the gods'). They used the tree's beans as currency - 100 beans would buy a slave, 12 beans the services of a courtesan and 10 beans a rabbit."
“...They used the tree’s beans as currency...12 beans the services of a courtesan and 10 beans a rabbit.”
So a guy with 12 beans had to ask himself; “Am I hungry or horney?”
