|A beautiful young lady goes to new doctor for an annual exam. After completing his exam the Dr. asks the girl to get dressed and wait outside.|
After a while he calls her back and tells her that all her tests came out fine, she was in perfect health.
"There was just one thing that bothers me," he said. "It's those calluses on your knees."
The girl began blushing and said, "That has to do with my love making!"
The doctor was confused and asked, "What has love making to do with your knees?"
She replied, "I do it quite often, and always doggie style."
The Dr. replied, "Don't you know any other style?"
The girl said, "Oh yes, of course I do, but the dog doesn't!!!"
