A guy was traveling 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 the guy. "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!" he exclaims. "I have a picture of Ronald Reagan tattooed on one butt cheek and a picture of George Bush on the other." - "This I gotta see," replies the agent. With that, the man drops his pants and bends over in front of the agent. - "By golly, you're right!" exclaims the agent. "Go on home to Boston." - "Thanks!" he says. "But how did you know I was from Boston?" - The agent replies, "I recognized the picture of John Kerry in the middle."
