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.""
