Two ministers doing missionary work in the South Seas are captured by a tribe and tied to stakes. The chief says to them, "You have a choice – death, or ugga bugga."
The first guy says, "Well, I guess ugga bugga." The chief shouts "UGGA BUGGA!" and 30 members of the tribe attack and sodomize the first missionary.
The chief then asks the second minister, "Now you have a choice, death or ugga bugga."
He says "well, my religion does not allow me to choose ugga bugga, so I suppose it must be death." The chief says, "Very well," and shouts "DEATH. But first, UGGA BUGGA!"
