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. “No health insurance,” he croaked.
The nun asked if he had money in the bank. “No money in the bank,” he said.
“Do you have a relative who could help you?” the nun said.
“Just a spinster sister, who is a nun,” he said.
Perturbed, the nun said, “Nuns are not spinsters! Nuns are married to God!”
The patient replied, “Then send the bill to my brother-in-law.”
