A man walks up to the farmhouse and asks little Linda where her daddy is.
"If you're here to ask about the bull in the south pasture, he's guaranteed, and has papers, and breeding him costs $250"
"Little girl, I'm not here to talk about the bull in the south pasture..."
"Oh, well the bull in the east pasture has papers, but he's not guaranteed, and he's $200!" the little girl injects.
"I don't care about any darn papers!" the man starts.
"Oh, well the bull in the west pasture is guaranteed, but he ain't got no papers! Just $150" the little girl interrupts happily.
"I'm not here to discuss any guaranteed bulls!" shouts the man, getting red-faced.
"Then our bargain-breeder is in the south pasture, he's not guaranteed, and got no papers, but he's just $100!" said the little girl.
"Listen" said the man, "I don't want to talk about ANY bulls, I need to talk to your daddy about my little girl and your brother Elmer!"
"I better go get daddy then!" says the little girl "I don't know what he charges for Elmer!"
