Indigestion

So on this jungle island two cannibals from different tribes cross paths and the one says to the other, "How you doing?" He replies, "Not so good, belly ache".  Oh, responds the first, "What you been eating?"
"Missionaries". "Oh, what they look like"? "You know, brown robes, rope belt, short hair". The first cannibal says, "How you cook em?" " We boil in big pot, add a little bay leaf." Oh, I know what wrong, you cook em wrong. Them not boilers, them friars."
