They get captured and dragged back to village, where the cannibal chief then comes out and says, "You outsiders have trespassed onto my island! For this you must face: Death, or MAMBO!"

The two guys are like, what is mambo?

The chief replies, Mambo is every man in the village comes and fucks you in the ass.

So He turns to the first guy, What do you choose...

Well the guy thinks about it and say, Well, I wanna live, so give me mambo.

So the three day long ritual begins, and they fuck him in the ass! By now the second guy is like holy shit!

the ritual ends and the chief releases the first guy.

Now he turns to the second guy, what do you choose... death.. or MAMBO!?

Second guys says, "Fuck that! I'd rather die!"

IT HAS BEEN SPOKEN, Death by MAMBO!
