A woman went to a podiatrist complaining that her feet always hurt.
He immediately noticed that she was extremely bowlegged.
"Have you always been that way?" asked the podiatrist.
"No," she said, not until recently. "I've been fucking a lot doggie
"Well," said the podiatrist, "you are going to have to stop."
"I can't," she replied, "that's the only way my German Shepherd fucks."
