Paddy is walking along the beach and finds a lamp etc etc, ....genie says he's got two wishes only.
Paddy thinks hard and asks for a never-emptying bottle of Guiness.
Poof! A bottle of Guiness appears in his hand.
Paddy tests it out and chugs the bottle down whereupon it promptly filled up again.
"Tats noice tat is."
"And what do you want for your second wish?" asks the genie.
"Woil, tat bottle o' stout is pretty good, so I reckon Oi'l have me anoder one o' dem."
Cue groans, some of which are sure to be at Paddy's accent. I just can't do accents.
