I just love this one

A missionary met a lion as he was walking from one village to another.
The missionary fell to his knees and buried his face in his hands. Nothing seemed to be happening; the lion was silent. The missionary peeped through his fingers and saw the lion on its knees, its face buried in his paws. The missionary in a trembling voice, “I am praying to be delivered from the jaws of death. But what on earth are you doing?”
The lion growled, “I’m saying grace.”
