An Irishman is walking along the beach and sees a bottle lying in the sand. He picks it up, brushes it off, and out pops a genie.
"Since you have freed me from the bottle, I will grant you three wishes,” the genie says.
The Irishman thinks for a moment, then says, "I'm feeling a mite thirsty. I think I'll be wishing for a pint o’ stout."
Poof! A pint appears in his hand. He drinks it down and starts to throw away the bottle, when the genie says, "I'd look at that bottle again, if I were you.”
The Irishman looks and sees the bottle magically refilling with stout.
"That is a magic bottle,” the genie said, “and it will always fill back up after you finish it. Now, what other two wishes can I grant you?"
The Irishman nods at the bottle in his hand and says, "I'll be taking two more of these."
