A man suffered a serious heart attack and had open heart bypass surgery.  He awakened 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."
