A man suffered a serious heart attack and had open heart bypass surgery. He awoke from the surgery to find himself in the care of nuns at a Catholic hospital.
As he was recovering, a nun asked him questions regarding how he was going to pay for services. He was asked if he had health insurance.
He replied, in a raspy voice, "No health insurance."
The nun asked if he had money in the bank.
He replied, "No money in the bank."
The nun asked, "Do you have a relative who could help you?"
He said, "I only have a spinster sister, who is a nun."
The nun got a little perturbed and announced loudly. "Nuns are not spinsters! Nuns are married to God,"
The patient replies, "That's right! Send the bill to my brother-in-law."
