In a small town in Tennessee, Big Bubba decides it

In a small town in Tennessee, Big Bubba decides it's time for his son, 14-year-old Billy Bob, to learn the facts of life. He takes him to the local house of ill repute, which is fronted by a beauty parlor. Bubba introduces Billy Bob to the madam, and explains that it's time for his indoctrination to sex." The madam says, "Bubba, you've been such a good customer over the years, I'm going to see to your son personally." So the madam takes Billy Bob by the hand and leads him upstairs, where she completes his deflowering. Later, as they are walking downstairs the madam says, "Since this is your first time, I'm going to see that you get the full treatment before you leave, I'm going to give you a manicure, too." Two weeks later Bubba and Billy Bob run into the madam on the town's main street. Billy Bob is acting a little shy, so the madam smiles and says, "Well, Billy Bob, don't you remember me?" "Yes, ma'am," the boy stammers, "You're the lady that gave me the crabs and then cut off my fingernails so I couldn't scratch 'em."
