A guy traveling through Mexico lost his wallet and all of his identification. Cutting his trip short, he attempted to make his way home, but was stopped by a US Customs agent at the border. "May I see your identification, please?" asked the agent. "I am sorry, but I lost my wallet," replied the guy. "Sure buddy, I hear that every day. No ID, no entry." Said the agent. "But I can prove that I am an American!" I have a picture of Ronald Regan tattoed on the side of my butt, and of George Bush on the other." "This I gotta see." Replied the agent. With that the guy dropped his pants and showed the agent his behind. "By golly, you are right." Said the agent. "Have a safe trip back to Chicago." "Thanks!" He said. "But how did you know I was from Chicago?" The agent said, "I recognized Obama in the middle."
