There was once a man who refused to attend funerals.
Then, when his own child died, he did not know how to prepare the body or where the burial ground was. So he put the child on his head and went about asking, "Where are the graves?"
Nobody would tell him.
He kept on wandering and asking, and as time passed, the dead body decayed and dripped down his nose. He kept asking, "Where are the graves? Ku malembe, kwa-kwa-kwa?"
Eventually he became a hornbill bird with his strange beak and strange cry: "Where are the graves? Ku malembe, kwa-kwa-kwa?"
