Two old men were arguing the merits of their doctors. The first one said, "I don't trust your fancy doctor. He treated old Jake Waxman for a kidney ailment for nearly a year, and then Jake died of a liver ailment."
"So what makes you think your doctor is any better?" asked his friend.
"Because when my doctor treats you for a kidney ailment, you can be sure you'll die of a kidney ailment."
"What are the chances of my recovering?" asked the bedridden man.
"One hundred percent," the physician reassured him. "Medical records show that nine out of ten die of the disease you have. Yours is the tenth case I've treated. Others all died. Statistics are statistics. You'll be fine soon enough."
