Mr. Smith was brought to Mercy Hospital (a Catholic hospital),
 and taken quickly in for coronary surgery. The operation went
 well and, as the groggy man regained consciousness, he was
 reassured by a Sister of Mercy, who was waiting by his bed.
 
 "Mr. Smith, you're going to be just fine," said the nun, gently
 patting his hand. "We do need to know, however, how you intend to
 pay for your stay here. Are you covered by insurance?"
 
 "No, I'm not," the man whispered hoarsely.
 
 "Then can you pay in cash?" persisted the nun.
 
 "I'm afraid I cannot, Sister."
 
 "Well, do you have any close relatives?" the nun questioned
 sternly.
 
 "Just my sister in New Mexico," he volunteered. "But she's a
 humble spinster nun."
 
 "Oh, I must correct you, Mr. Smith. Nuns are not spinsters - 
 they are married to God."
 
 "Wonderful," said Mr. Smith. "In that case, please send 
 the bill to my brother-in-law."
