Three guys are captured by a tribe of natives in a far off land. They are brought before the tribal leader who gives them a choice. He says, "what will you have, death or bunga?". The first guys thinks, hmmm wonder what bunga is. "I'll take the bunga". The tribal leader says, "good". Then a dozen tribal members line up and give it to him in the rear.
The tribal leader turns to the second guy and gives him the choice, death, or bunga. The second guy thinks, hmm, that bunga thing is pretty nasty. But death is permanent, "I'll take the bunga". Tribal leader says, "good", and a hundred tribesmen line up and give him the bunga.
The tribal leader gives the choice to the third captive. He thinks a while, hmm, first it was a dozen, then it was a hundred, I don't know man. Heck with it, "I'll take death". The tribal leader says, "good, death .... by bunga".
