Once a man bought a horse. You had to say ?hallelujah? to make it go 
and ?amen? to make it stop.

The man was riding his horse one day but then he realized he was riding 
to an edge of a cliff.

He was so scared he forgot how to make the horse stop. He thought this 
was the end of his life and he started praying, ending the prayer by 
saying ?amen?.

The horse suddenly stopped at the edge of the cliff. ‘hallelujah’ said 
the man with a sigh of relief and off went the horse?
