''Thank God''
A man needed a horse, so he went to a church and got one.
Before he left, the priest told him that it was a special horse.
In order to make the horse go, you say, ''Thank God'', and for it to stop you say, "Amen".
So the man left, and a few minutes later he dozed off on his horse.
Hours later, he woke up and his horse was racing him towards the edge of a cliff.
Just in time, he shouted "Amen!" and the horse stopped a few inches from the edge.
"Whew," said the man, "Thank God!"
