Two Irish nuns have just arrived to the USA by boat and one says to the other, "I hear that the people in this country actually eat dogs."
"Odd," her companion replies, "but if we shall live in America, we might as well do as the Americans do."
Nodding emphatically, the mother superior points to a hot dog vendor and they both walk towards the cart.
"Two dogs, please," says one.
The vendor is only too pleased to oblige and he wraps both hot dogs in foil and hands them over the counter. Excited, the nuns hurry over to a bench and begin to unwrap their "dogs."
The mother superior is first to open hers. She begins to blush and then, staring at it for a moment, leans over to the other nun and whispers cautiously: "Which part did you get?"
It was a celebratory mood with the boys at NASA; they had just made the scientific achievement of a lifetime.
As they were uncorking a bottle of champagne, Dr. Lowenstein, the head scientist at NASA, asked everyone to be quiet as he had received a congratulatory phone call from the President of the United States.
He picked up a special red phone, and spoke into it.
"Mr. President," said Dr. Lowenstein, grinning broadly, "after twelve years of hard research and billions of dollars spent, we have finally found intelligent life on Mars."
He listened for a second, and his smile gradually disappeared, replaced by a frown.
He said, "But that’s impossible... we could never do it. Yes Mr. President,” and hung up the phone.
He addressed the crowd of scientists staring at him curiously.
"I have some bad news," he said, "the President said that now that we’ve found intelligent life on Mars... he wants us to try to find it in Congress."
