An Alaskan woodpecker and a Texas woodpecker were in Alaska arguing
about which state had the toughest trees to peck.

The Alaskan
woodpecker said that they had a tree that no woodpecker can peck.

The Texas woodpecker challenged him and was able to peck a hole in the
tree with no problem.

The Alaskan woodpecker was in awe.

The Texas
woodpecker challenged the Alaskan woodpecker to peck
a tree in Texas that no woodpecker had been able to peck
successfully.

The Alaskan woodpecker expressed much confidence that
he could do it.

After flying to Texas and successfully pecking the
tree in Texas, the two woodpeckers couldn't figure out why the Texas
woodpecker was able to peck the Alaskan tree and the Alaskan
woodpecker was able to peck the Texan tree when neither one was able
to peck the tree in their own state.

After thinking for some time
they both came to the same conclusion:

Your pecker is always harder when you're away from home.
