Hillbilly Newlyweds

A newly married hillbilly couple decided they wanted children, but didn't know
how to go about it. Questions and conversations with friends and relatives
proved no help, until a neighbor said they should go to town and ask the Big
City Doctor. The doctor let them look at a child's book about where babies came
from, but to no avail. He tried his own explanation but was met with blank
stares. Exasperated, he took them to his private office, and showed them a porno
movie. This was also useless. Angrily, he ordered the girl to strip, told the
man to watch, and had sex with her on the couch.
''Now, do you understand?'' he asked.
''I just have one question. How many times a week do I have to bring her in
for this?''
