A fairy walks into a bar and sits down next to an Irishman. He turns to her and says "hey, can you grant me three wishes?"
"Sure, what'll it be?"
"I want a pint of beer that is never empty."
She waved her wand, and *poof* a pint of cold beer appeared on the
bar. The man grabbed it, downed it in one gulp and by the time he had
placed it back on the bar it was full.
"So what's your next wish?"
"I'll take two more of these."
