Two missionaries in Africa get apprehended by a tribe of very hostile cannibals who put them in a large pot of water. They build a huge fire under it, and leave them there. A few minutes later, one of the missionaries starts to laugh uncontrollably. The other missionary cant believe it!

He says, Whats wrong with you? Were being boiled alive! Theyre gonna eat us! What could possibly be funny at a time like this?

The other missionary says, I just peed in the soup!
