Two men were walking through a field one day when they spotted an angry old bull who wanted them out of his pasture. Instantly, they darted toward the nearest fence. The storming bull followed in hot pursuit and it was soon apparent that they wouldn't make it.
Terrified, one man shouted to the other, "Put up a prayer right now, John! That bull is about to catch up to us!
But John answered right back, "I can't. I've never made a public prayer in my entire life!"
"But you must!" yelled his companion. "The bull is catching up to us. Just use a prayer you have heard before!"
"All right," panted John, "I'll say the only prayer I know, the one my father used to repeat at the table at Thanksgiving: 'O Lord in Heaven, for what we are about to receive, make us truly thankful. Amen!'"
