Two missionaries in Africa get apprehended by a tribe of very hostile 
cannibals who put them in a large pot of water, 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 can't believe it! He 
says, "What's wrong with you? We're being boiled alive! They're gonna eat 
us! What could possibly be funny at a time like this?" 

The other missionary says, "I just peed in the soup."
