Man walks into a pub, places a large cerdboard box on the bar and orders a drink.
Curiosity gets the better of the barman and he asks what is in the box.
The man opens the box and takes out a tiny piano, followed by a tiny piano stool, then a tiny man who sits at the piano and proceeds to play Beethovens Moonlight Sonata.
'That's amazing exclaims the barman, where did you get it?'
The man replies that he was given a token which granted him a wish. As he had used his wish he offered it to the barman, but warned him to use it wisely and be careful what he wished for.
The grateful barman thanked the man and pondered the situation carefully before saying 'I wish I had a million bucks!'
Nothing much happened for a moment, then the door of the pub opened slightly and in waddled a little duck, closely followed by another, then another and another. Very soon the pub was filled with little ducks.
'What's happening?' exclaimed the barman, 'I asked for a million bucks, not a million ducks!'
'Well', replied the man, 'you didn't really think that I wished for a twelve inch pianist did you?'
'It's not a proper slider'
