One day, Billy Bob came home to excitedly tell Cletus some good news.
"Daddy, Daddy, guess what? I's found the girl I wants to marry!"
"Now hold on a second, what's this all about?"
"Well, I met this girl... an' she's the purtiest thing I ever seen! An' she can cook, an' clean, an' -- you won't believe this, Daddy -- she's even a virgin!"
"Boy, I won't allow it. That girl ain't right for you."
(tearfully) "But Daddy, why? She's perfect, an' we love each other!"
"Listen here, boy. If she ain't good enough for her own family, what makes you think she's good enough for ours?"
