Nuns at the Hospital

A man suffered a serious heart attack and had bypass surgery. He awakened to find himself in the care of nuns at a Catholic hospital. As he was recovering, a nun asked how he was going to pay the bill. 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, "Just a spinster sister, who is a nun." The nun, slightly perturbed, said, "Nuns are not spinsters! Nuns are married to God." The patient replied, "Then send the bill to my brother-in-law."
