0be's mumbo jumbo has big mojo.
“Be careful what you do,
Or Mumbo-Jumbo, God of the Congo,
And all of the other
Gods of the Congo,
Mumbo-Jumbo will hoo-doo you,
Mumbo-Jumbo will hoo-doo you,
Mumbo-Jumbo will hoo-doo you.”
- by Vachel Lindsay (who was not black, but was a friend of the poet Langston Hughes, who was black, if it matters).
