Go on! You can't tease us like that
It doesn't seem so funny in print but here you go:-
Paddy found himself marooned on a desert island and came across an old lamp so he rubbed the sand off it and POOF a genie appeared in front of him.
'I'm the Genie of the lamp it said and I grant you three wishes."
'To be sure,' said the Genie in his best Irish accent.
'Well then,' said Paddy 'I'll be having a bottle of nice cool Guinness if you please.'
The Genie waved his hands in the air and said a few magic words and POOF a bottle of the cool black stuff appeared from nowhere.
Paddy downed most of it in three giant gulps then sat back and belched.
As he watched, the bottle filled itself up until it was once again full to the brim.
'Bejesus.' said Paddy. 'Did you see that? It filled itself back up, just like that.'
'Yes,' said the Geni. 'It does that.'
'And I have two more wishes?' asked Patrick.
'To be sure you do,' said the Geni, entering into the spirit of things.
Paddy thought for a moment then held his bottle of Guinness in the air. 'In that case, I'll be having two more of these, if you please.'
