Canadian woodpeckers

[Viper®]

An Alberta woodpecker and a Newfoundland woodpecker were arguing about which place had the toughest trees.
The Alberta woodpecker said Alberta had a tree that no woodpecker could peck.
The Newfoundland woodpecker accepted his challenge and promptly pecked a hole in the tree with no problem. The Alberta woodpecker was amazed.
The Newfoundland woodpecker then challenged the Alberta woodpecker to peck a tree in Newfoundland that was absolutely
im-peckable (a term woodpeckers like to use). The Alberta woodpecker expressed confidence, said he could do it and accepted the challenge.
So the two flew to Newfoundland where the Alberta woodpecker successfully pecked the so-called im-peckable tree with no problem.
Both woodpeckers were terribly confused. How is it that the
Newfoundland woodpecker was able to peck the Alberta tree and the Alberta woodpecker was able to peck the Newfoundland tree, yet neither was able to peck the tree in their own province????

After much woodpecker pondering, they both came to the same conclusion:
Apparently your pecker gets harder when you're away from home!
