This fundamentalist Christian couple felt it important to own an equally
fundamentally Christian pet.  So, they went shopping.
At a kennel specializing in this particular breed, they found a dog they
liked quite a lot.  When they asked the dog to fetch the Bible, he did it 
in a flash.  When they instructed him to look up Psalm 23, he complied 
equally fast, using his paws with dexterity.  They were impressed, 
purchased the animal, and went home (piously, of course).
That night they had friends over.  They were so proud of their new
fundamentalist dog and his major skills, they called the dog and showed 
off a little.
The friends were impressed, and asked whether the dog was able to do any 
of the usual dog tricks, as well.  This stopped the couple cold, as they 
hadn't thought about "normal"  tricks.
Well, they said, "let's try this out."
Once more they called the dog, and they clearly pronounced the command,
"Heel!"
Quick as a wink, the dog jumped up, put his paw on the man's forehead,
closed his eyes in concentration, and bowed his head.
