In Africa, divorce is known for money, the so-called "Nigerian Letters". Materials of Wikipedia.

My name is Bakare Tunde, I am the brother of the first Nigerian astronaut, Major of the Nigerian Air Force, Abaka Tunde. My brother became the first African cosmonaut to go on a secret mission to the Soviet station Salyat-6 in the distant 1979. Later, he took part in the flight of the Soviet Union T-16Z to the secret Soviet space station Salyat-8T. In 1990, when the USSR fell, he was on the station. All Russian crew members were able to return to the ground, but my brother did not have enough space on the ship. Since then until today, it has been forced to be in orbit, and only a few Progress cargo ships supply it. Nevertheless, my brother is not losing his spirit, but he is eager to return home, to his native Nigeria. Over the long years he spent in space, his gradually accumulating salary amounted to $15 million. Currently, this amount is stored in a bank in Lagos. If we get access to the money, we will be able to pay Roscosmos the required amount and arrange a flight to Earth for my brother. The amount requested by Roscosmos is $3 million. However, we need your help to get the amount, as we, Nigerian public servants, are prohibited from all transactions with foreign accounts. Forever yours, Dr. Bakare Tunde, the leading specialist in astronautics.
