"Gentlemen, I'm afraid Heaven is full - we just don't have room for you here," said St. Peter. "But, St. Peter, surely you recognize me!" the first doctor exclaimed. "I developed the DNA theory, and have helped improve millions of lives through my work." St. Peter shook his head, thinking, and finally said, "You're right, we just have to let you in. Come on -- we'll make room somehow."
"And I know you recognize me, St. Peter," the second doctor said. "I developed the MRI, and because of my machine, millions of people with medical problems are helped." Again St. Peter is moved. "Yes, come on in. Surely you deserve to be here, too," he replies.
Finally, the last doctor pipes in, "St. Peter, You must also know me -- I'm the doctor who developed HMOs." To this St. Peter only hesitates a moment, and then replies, "Yes, you, too, have a place in Heaven -- but you can only stay 3 days."
Suh-LAM! For more laughter, you know where to go...
