A woman goes to the doctor complaining of bad knee pains. After
the
diagnostic tests showed nothing, the doctor questions her, "There
must
be something you're doing that you haven't told me. Can you think
of
anything that might be doing this to your knees?"
"Well," she said a little sheepishly, "my husband and I have sex
doggy-
style on the floor every night."
"That's got to be it," said the doctor. "There are plenty of
other
positions and ways to have sex, you know."
"Not if I'm going to watch TV, there isn't," she replied.
