Joke - The Amen Horse

There was a guy who had been lost in the desert for about two weeks. One hot day, he spies a shack, crawls to the doorstep and collapses. Turns out it's the home of a missionary, who nurses the traveler back to health.

After getting better, the man asks for directions to the nearest town. On his way out the backdoor, he spots the missionary's horse. "Could I borrow your horse, and return it back when I reach the town?"
      
The missionary, being a good Christian, says yes, but with a warning. "There is a special thing about this horse. You have to say 'Thank God' to make it go and 'Amen' to make it stop."
      
Not paying much attention, the man says, "Sure, okay."
      
So he gets on the horse and says, "Thank God" and the horse starts walking. Then he says, "Thank God, thank God," and the horse starts trotting. Feeling really brave, the man says, "Thank God, thank God, thank God, thank God, thank God" and the horse just takes off galloping.

Pretty soon the man realizes they're approaching a cliff! He begins to do everything he can to make the horse stop.
      
"Whoa! Stop! Hold on!"
      
Finally he remembers! "Amen!"
      
The horse stops four inches from the cliff! Then the man leans back in the saddle and says, "Thank God."
