Dog playing poker...

An old Justin Wilson story:

There was a poker game one time that down in Cajun country at a saloon and it was hot, yeah, I guarantee! They had them a rule that if one man got up from the table he had to have his-self someone to fill his seat. So, there was an old dog there that would sit at the table while a man took a break and got his-self a drink... like some of that pop with the froth on top. A man walked into that bar and saw the dog sittin' at the table playin' poker. He says to the man at the bar, "That dog must be pretty smart to be able to play poker!" "Nah," he replied, "He ain't so smart.... every time he get a good hand he wag his dang tail!"
