A good man suffered a sudden serious heart attack, and had immediate lifesaving open heart bypass surgery. He awakened to find himself in the care of nuns at a Catholic hospital. As he was recovering from surgery, a nun asked him questions regarding how he was going to pay for his treatment. She asked if he had health insurance.
He replied, in a weak 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 with the cost?"
He said, "I only have a spinster sister, who is a nun."
The nun became agitated, and said loudly, "Nuns are not spinsters! Nuns are married to God."
The patient replied, "Then send the bill to my Brother-in-law."
