1.- A man walks into a bar and asks for a drink. The bartender pulls out a gun and points it at him. The man says, "Thank you," and walks out
2.- An ordinary American citizen, with no passport, visits over thirty foreign countries in one day. He is welcomed in each country and leaves each one of his own accord.
Solution
1.- The man has hiccups; the bartender scares them away by pulling a gun.
2.- He is a mail courier who delivers packages to the different foreign embassies in the United States. The land of an embassy belongs to the country of the embassy, not to the United States.
