Growing up in Tulsa, a town full of evangelists, I heard many jokes about them. I sometimes babysat for some of the grandchildren of T. L. Osburn, (I believe the foundation & museum is still in Tulsa) who spent most of his life, along with his wife Daisy, as a missionary in Africa told this one, which Daisy said really happened to him:
   The Irish missioner was preaching to the African tribe. "And I say to you that you must love your fellowmen!"
"Moolagumbi!" shried the natives.
   "White man and black man must learn to co-operate."
   "Moolagumbi!" chanted the crowd.
The missioner was very pleased & he told the chief how pleased he was with the reception.
   "I am glad, O man of Ireland," said the chief, "but be careful as we pass my cattle that you do not step into the moolagumbi."
