Game Warden

A farmer and his friend were leaning on a fence chatting. Suddenly, the local Game Warden showed up and insisted on checking the farmer's property and, in particular, a certain field. The farmer refused to allow him access to the field but the Warden insisted he had the right, saying, "I'm the Game Warden and I have a card! This card allows me to go in." Before the farmer could stop him, the Warden was off into the field. Soon, a horrifying scream pierced the air and the Warden, being chased by a massive bull, reappeared running for his life. "Help, help!" he cried. The farmer shouted back, "Show him your card! Show him your card!"
