A Hawaiian woodpecker was arguing with a Californian woodpecker about which state had the hardest trees. The Hawaiian woodpecker said Hawaii had a tree that no woodpecker could peck, but the Californian woodpecker accepted the challenge and promptly pecked a hole in the tree, no problem. The Californian woodpecker then challenged the Hawaiian woodpecker to peck a tree in California that was absolutely unpeckable. The Hawaiian accepted the challenge, flew to California, and did so, no problem. Now the two were confused. Why could the Californian woodpecker easily peck the Hawaiian tree and the Hawaiian woodpecker easily peck the Californian tree, but neither could peck the tree in their own state? Finally, they came to the conclusion: your pecker is always harder when you're away from home!
