Who is Boo-Boo the Fool? A listener wonders if this African-American character has any relation the Puerto Rican fool, Juan Bobo. Martha draws a connection to the Spanish term bobo, meaning “fool,” and its Latin root balbus, meaning “stammerer”. Grant notes that the name Bobo has been extremely common for clowns since at least the 1940s, and the bobo/clown/jester character is prevalent in most all cultural folklores, be they African, South American, or Anglo-European. This is part of a complete episode.
