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, your pecker gets harder when you're away from home.
