Irishman finds a Genie lamp and rubs it. Out comes the Genie and asks
"Master you have released me from the lamp and I grant you three wishes, what would you like"
Irishman scratches his head, then answers
"A bottle of Guinness that never gets empty. "
"Granted master" retorted the Genie and produced the bottle.
The man was delighted and got drunk on this one magic Guinness bottle for weeks then he remembered that he had two other wishes. He rubbed the lamp again and the Genie appeared.
"Yes master, you have two more wishes, what would you like?"
"You know that magic, never ending Guinness bottle" he asks the Genies. "Well, for my final two wishes, I'd like another two of them"
