''Whew!''
A guy needed a horse, so he went to a monastery and got one.
Before he left, the head monk told him that it was a special horse.
In order for it to go, he should say “Thank God”
and for it to stop he should say “Amen”.
So, the guy went off, and a few minutes later he started to doze off.
A few hours later, he woke up and was heading for the edge of a cliff.
So, he shouted “Amen!” and the horse stopped a few inches from the edge.
“Whew,” he said. “Thank God.”
