An Irishman is sitting at the end of a bar. He sees a lamp at the end of the table. He walks down to it and rubs it. Out pops a genie. It says, "I will give you three wishes." The man thinks awhile. Finally he says, "I want a beer that never is empty." With that, the genie makes a poof sound and on the bar is a bottle of beer. The Irishman starts drinking it and right before it is gone, it starts to refill. The genie asks about his next two wishes. The man says, "I want two more of these."
