Once, four friends were playing poker. Their fifth friend, Jimmy, asked to join them, so they said "Sure! Ante up." A few rounds later, they realized that Jimmy was very, very bad at poker. It seemed like he didn't know how to play at all! He kept mixing up all the suits of the cards, calling hearts 'petals' and clubs 'clovers' and diamonds 'stars' and spades 'shovels'. Finally, they got fed up with Jimmy saying everything wrong, so Bob, the oldest, said "Wouldja stop already, Jimmy! You're confusing everyone. Just call a spade a spade!"
