A Mexican woodpecker and a Canadian woodpecker were in
 Mexico arguing about which country had the toughest trees.
 The Mexican woodpecker claimed Mexico had a tree that no
 woodpecker could peck.
 
 The Canadian woodpecker accepted his challenge and promptly
 pecked a hole in the tree with no problem. The Mexican
 woodpecker was amazed.
 
 The Canadian woodpecker then challenged the Mexican
 woodpecker to peck a tree in Canada that was absolutely
 'impeckable' (a term frequently used by woodpeckers ). The
 Mexican woodpecker expressed confidence that he could do it
 and accepted the challenge.
 
 The two of them flew to Canada where the Mexican woodpecker
 successfully pecked the so-called 'impeckable' tree almost
 without breaking a sweat.
 
 Both woodpeckers were now terribly confused. How is it that
 the Canadian woodpecker was able to peck the Mexican tree,
 and the Mexican woodpecker was able to peck the Canadian
 tree, yet neither was able to peck the tree in their own
 country?
 
 After much woodpecker pondering, they both came to the same
 conclusion:
 
 Apparently, Tiger Woods was right when he said, "your pecker
 gets harder when you're away from home."
