3 explorers are lost in the amazon...

...and are found by tribe known to be unfriendly to outsiders. The 3 explorers are bound and brought before the chief. The great chief, with the whole village watching, declares the explorers each have a choice... Death! or Bulla Bulla! The first explorer looks at the other two and says, "well, nothing can be worse than death, I'll take Bulla Bulla.." The whole village cheers and the first explorer is then stripped down, tied to a tree, and every man in the village screws his ass. As the first explorer is nearly unconscious from pain and moaning on the ground, the second explorer is faced with a grave decision. He says, "well, death looks like a good option, but he's still alive and I want to get out of this somehow, I guess I'll take Bulla Bulla." The whole village cheers even louder, and the second explorer is stripped, tied to a tree, and every man gets to screw his ass, only this time, they can last even longer cause they just had the first explorer. This long and painful event finally comes to end, and the 1st and 2nd explorers are lying in a heap, looking like they'll never walk again. The third guy is like, holy crap, screw that, I'll take death over that level of pain any day, just end it chief. The Chief smiles, looks out at the expectant crowd and says, "Death....

...by Bulla Bulla!!"

I'm sure there's many variations to this one, just heard one the other day, enjoy!
