Bill was living alone in a little wooden house on the coast of Scotland. He wasn't living a healthy life, way too much whiskey and beer. And a heavy smoker on top of that.
One Saturday afternoon he set off for the village pub. It was two miles away, but he took a shortcut along the beach. That was when he noticed a bottle washed up on the shore. There's nothing special about that, but this bottle still had a cork in it. The cork was protruding a little from the opening in the bottle and Bill was not one to leave a bottle like that unexamined.
He managed to pull the cork out, but only to find that the bottle was empty. He was about to throw it in the sea, when suddenly there was a sound like some sort of gas flowing out the bottle. And then there was a voice:
"Master, you have released me from my glassy prison. I'm at your service. Command, and I will fulfil two wishes for you"!
Bill hesitated. Then he had an idea. "I would like a bottle of whiskey that fills up again every time you drink of it."
As soon as he had said that he stood there with a bottle of fine Scottish whiskey in his hand. He couldn't believe his luck. He took a liberal sip - and the bottle filled up again. He did this several times, and every time the bottle filled up. He was beginning to enjoy himself.
Then there was an impatient voice from the bottle. "Master, I must move on. What is your second wish?".
Bill thought hard for some time. Then a smile came on his face :"I'd like another bottle like that", he said.
