A poor old 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 how he was going to pay for his treatment.
She asked, "Do you have health insurance?" He replied in a raspy voice, "No health insurance."
The nun asked, "Do you have money in the bank?" He replied, "No; 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 became agitated and announced loudly, "Nuns are not spinsters! Nuns are married to God."
The patient replied, "Good; then please send the bill to my brother-in-law."
