Rhinosaur

After he had strapped himself into the seat, he waited for the ship's computers to bring him down safely. What he didn't know, was the little blue planet's name- "Earth".
Within a short while of entering this earth's atmosphere, he landed in this small country called "Cuba". He didn't have any press or TV crews present to welcome and harass him, but that was only because they were told not to enter the country, and those intrepid enough to enter despite the warnings were shot and thrown right back to where they came from. (I know, its shocking, the waste of ammunition, but the country was then ruled by this maniacal despot with lots of bullets in his armoury.)
The first thing the little green alien was asked on disembarking was, "Are you an American?" When he replied to whoever it was that asked him the question that he did not KNOW what an American was, let alone be one, the Cubans were very hospitable. Being of a smarter race, he managed to sell his spaceship for US$3,200,000,000 on a hire- purchase agreement with the maniacal despot of Cuba. (The Cubans DID try to bargain by trying to deduct import duty, but didn't when the alien asked them to prove that he exported the ship from somewhere...)
The government of the United States of America, another country, also bid for it, but what they didn't have, was the spaceship within their political boundaries already. Cuba sold the ship to the US, of course, at the same price- and some bullets (shipping extra)- US$3.2B, but they settled for cash up front so they could live off the interest earned. What they also managed to do was reopen trade with the USA, and made a killing selling Cubans (cigars, not citizens) in the first month. After that, the novelty wore off, and so did the desire for them- there's this thing about contraband you'll never get in legally imported goods. Cuba also had to rework its economy since they now had so much money.
One more thing the Cubans tried was banking, what with the money and all. People put a lot of money and trust in them, so much that the Swiss went, well, bankrupt. They converted their banks to hotels and their vaults to solitary confinement areas for the worst criminals in the world.
The Cubans, in the meanwhile, tried to replace their poppy plantations with actual coffee ones but they just couldn't switch to a life of uprightness and honour. In the end the despot pocketed the $3.2B, closed trade ties, and all was well except for the occasional planeload of heroin being shot down, or a shipload of brown sugar being sunk by another country. (You ever wonder what governments do with confiscated narcotics?)
And the worst criminals in the world? They got got lost in transit while being returned...
