Well, my entrie for the 'I dream of a jeanie bottle'-create-a-genie-contest!
Meet Ginny. Originally Irish, but living in The Netherlands, she travelled with a VOC-ship in the Dutch golden age, to trade with the Indonesians of that time. But unfortunately was the ship not heavy enough, and when they ended up in a storm the ship capsized, and everybody had to swim. Ginny couldn't swim, but she found this bottle that could strangely enough hold her. But after a while Ginny's arms began to hurt, and after days without food, she managed to climb in the bottle. Don't ask me how she did that. The magic in the bottle (because it was magic that made the bottle float) went into Ginny, and this way she became a bottle genie.
However, the story isn't over already! An Arabian fisherman found the bottle, and brought it home, where he found the genie. It was a cute guy, and Ginny wasn't too harsh not to grant him some wishes. They had a good time. The fisherman saw his dreams fulfilled, and Ginny saw her life having a meaning. But, the fisherman lived in a desert (Yes, he did. Don't ask my why he became a fisherman), and he often wished some water, because the climate makes you quite thirsty there. So, that day he wished for a lot of water, and Ginny thought, bored by again fulfilling the same wish: 'I'll give him enough water for the rest of his life'. At that moment a whole lake of water fell on that spot, overflowing the house and everything in its neighbourhood. A little sea was formed that day, and that sea made a river to the Mediterranean Sea. The water took everything with it, and one of those things was Ginny's bottle. But, having no magic in it, it couldn't float, and Ginny sank to the bottom of the sea, lying there for a hundred years, until sunmk is doing something with it.
(Oh, you can still find the remnants of the river. It is now part of the Suez-canal.)
