A city fella out in the country for a drive stops at a small Pub for a beer.

When he walks in he notices a table with four chairs where some poker is being played.

Looking closer he sees there is actually a cattle dog on one chair playing cards.

He comments "wow that sure is one really clever dog being able to play cards"

The farmer replies drly "he aint that bloody clever, every time he gets a good hand he wags his tail"
