Two Afghanis are taking a shower when one notices the other has a huge cork stuck in his butt.
"If you do not mind me saying," said the second, "that cork looks very uncomfortable. Why do you not take it out?"
"I cannot", lamented the first Afghani. "It is permanently stuck in my butt."
"I do not understand," said the other.
The first Afghani says, "I was walking through the desert and I tripped over an oil lamp. There was a puff of smoke, and then a huge old man in red, white and blue attire, with a white beard and top hat came oozing out.
"He said, 'I am Uncle Sam, the Genie. I can grant you one wish.'"
And I said, "No shit."
