Three explorers go to deepest darkest Africa and are captured by savages. They are taken to the chief and given two options: Death or Booga Booga.
The first explorer thinks that certainly nothing can be worse than death, so he picks booga booga.
To administer booga booga the chief calls on his most enormous (in every way) warrior. The explorer is viciously sodomized, passes out, bleeds, etc.
The second explorer also chooses booga booga and suffers a similar experience.
Seeing this, the third explorer thinks to himself that booga booga is a fate worse than death and decides to choose death.
What!?! exclaimed the chief. He was dumbfounded. Nobody had ever chosen death before. How would the explorer be put to death?
Aha! said the chief. I know! Death by booga booga!
