A man finds a lamp. He rubs it and a Genie emerges. The Genie tells him he will be granted three wishes. The man thinks for a moment and says, "First, give me a bottomless mug of beer."
A mug of beer appears in his hand. He sips it once, then again and the mug is magically refilled. The man is thrilled and continues to drink. The mug never empties.
Then the Genie says, "And what about your other two wishes?"
The guy thinks for a moment and says, "Give me two more just like this one!"
