Joe was travelling through Mexico on vacation when, lo and behold, he lost his wallet and all identification. Cutting his trip short, he attempts to make his way home but is stopped by the Customs agent at the border. "May I see your identification, please?", asks the agent. "I'm sorry, but I lost my wallet", replies Joe. "Sure, buddy, I hear that every day. No ID, no crossing the border", says the agent. "But I can prove that I'm an American!" exclaims Joe. "I have a picture of Bill Clinton tattooed on one butt cheek and a picture of Bob Dole on the other." "This I gotta see", replies the agent. With that, Joe drops his pants and bends over in front of the agent. "By golly, you're right!", exclaims the agent. "Go on home to Massachusetts." "Thanks", says Joe, "but how did you know I was from Massachusetts?" The agent replies: "I saw the picture of Ted Kennedy in between."
