Every week one of the Nuns placed a one thousand dollar bill in the collection plate. This went on for weeks until the priest, overcome by curiosity, approached her. "Sister," the priest said, "I couldn't help but notice that you put $1,000 a week in the collection plate." "Why, yes, Father," she replied. "Every week my son sends me money, and what I don't need I give to the church." "That's wonderful! How much does he send you?" asked the priest. "Oh, $20,000 a week or so." "Your son is very successful," said the priest. "What does he do for a living?" "He is a veterinarian," she said. "That's quite an honorable profession," said the priest. "Where does he practice?" "Well, he has one cat house in Las Vegas and another in Reno."
