My favorite genie joke.

An Irish farmer was tending to his land when he discovered a magic lamp. He rubbed the lamp and a genie appeared.
"For releasing me from my prison, I shall grant you any three wishes," he says. "Now, what is your first wish?"
The farmer says, "I want the Huns to attack Ireland!"
The genie questions the farmer, confused, but the farmer insists. The genie grants th wish, and the Huns begin their raid, killing, stealing, raping and pillaging all the way to Ireland and back.
The genie then asks, "And what for your second wish?"
The farmer replies, "I want the Huns to attack Ireland!!"
The genie begins to protest, but the farmer once again insists. And so once again the Huns begin a raid, killing, stealing, raping and pillaging all the way to Ireland and back.
The genie then asks, "And for your final wish?"
The farmer replies, "I want the Huns to attack Ireland!!!"
Without questioning this time, the genie grants his wish, and the Huns begin a final raid, killing, stealing, raping and pillaging all the way to Ireland and back. The genie then bids the farmer farewell, and vanishes.
40 years later, the same Irish farmer was tending to the same land when he discovered another magic lamp. He rubs the lamp, and a genie appears.
"Not you again," the genie exclaims. "I probably don't have to ask, but what is your first wish?"
The farmer says, "I want the Huns to attack Ireland!"
"Ok," the genie says, "I'm gonna grant your wish, but I need to ask you something. Last we met, you had the Huns attack Ireland three times. Why in the world would you want the Huns to attack Ireland *three times*?
The Irish farmer replies, "Because they would have had to have gone through England six!"
