There's this guy who had been lost and walking in the desert for
about 2 weeks. One hot day, he sees the home of a missionary.
Tired and weak, he crawls up to the house and collapses on the
doorstep. The missionary finds him and nurses him back to health.
Feeling better, the man asks the missionary for directions to the
nearest town. On his way out the backdoor, he sees this horse. He goes back
into the house and asks the missionary, "Could I borrow
your horse and give it back when I reach the town?" The missionary
says, "Sure but 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, ok." So he gets
On the horse and says, "Thank God" and the horse starts walking.
Then he say, "Thank God, thank God, " and the horse starts
trotting. Feeling really brave, the man say, "Thank God, thank
God, thank God, thank God, thank God" and the horse just takes off.

Pretty soon he sees this cliff coming up and he's doing everything
he can to make the horse stop. "Whoa, stop, hold on!!!!" Finally
he remembers, "Amen!!"

The horse stops 4 inches from the cliff. The man leans back in
the saddle and says, "Thank God".
