Canine Card Shark

Two dog owners were bragging about the intelligence of their pets. "The brightest dog I ever had," said one, "was a Great Dane that used to play cards. He was great at poker, but finally a friend complained about him and I had to get rid of him." "You got rid of him, a bright dog like that?" exclaimed his friend. "A dog like that would be worth millions." "Had to," the first man replied. "I caught him using marked cards."
